Removed the manual validation step because it is unnecesary (and annoying)
to gate this pipeline since it opens an unpublished, draft release.
The downstream triggered pipeline will gate the release to the VS Code
marketplace.
Instead of having to maintain an edited copy (which was really annoying)
I stubbed out `PSConsoleHostReadLine` to do what's expected.
So now we can just use the existing shell integration script directly!

Since we can't reliably find the script using
`code --locate-shell-integration-path pwsh` we now rely on it being sent
by the client on initialization. Its presence implies the feature is on.

This is pretty VS Code specific, but not necessarily so.

…artup (#2287)

Refactor the ProfilePathInfo structure to use a record type for simplicity. Ensure the profile variable is set during the startup process, regardless of whether profiles are loaded. This is to make behavior consistent with ConsoleHost and pwsh -noprofile ($profile is available regardless of if profiles were actually loaded or not)
Exposes the open editor documents to the PowerShell extension terminal so that users can query, save, or close documents from PS, enabling scripting scenarios.
Adds "F2" Rename Support via a provider that parses the AST for the variables. A disclaimer is present that this is only scoped for one script at a time.

…tests for registration options (#2296)

* Enhance RenameHandler to handle null capabilities gracefully and add tests for registration options

* Refactor RenameHandler to support nullable capabilities and enhance tests for registration options

* Address review: keep interface-compatible signature; cover explicit false capability

- Revert GetRegistrationOptions parameter to the non-nullable RenameCapability
  declared by IPrepareRenameHandler/IRenameHandler, and rely on the
  null-conditional check (capability?.PrepareSupport == true) for the runtime
  case where the framework passes a null capability. This matches the OmniSharp
  interface signature exactly, avoiding any nullable-annotation mismatch
  (e.g. CS8765) while remaining null-safe during initialize.
- Add explicit { false, false } theory cases for both handler kinds so the
  three distinct PrepareSupport inputs (omitted/null, true, false) are all
  covered and a regression that treats false as enabled would be caught.

Verified: src and test projects build with 0 warnings under #nullable enable;
all 6 GetRegistrationOptionsReflectsPrepareSupport cases pass on net462 and net8.0.

…e` (#2302)

* Drop unused `IEquatable` from range wrappers and fix `FoldingReference`

We had silenced CA1067 (types implementing `IEquatable<T>` without overriding
`object.Equals`/`GetHashCode`) instead of fixing it. Promote it to `error` and
resolve the offenders at the root.

The four wrapper structs in `EditorFileRanges.cs` — `OmnisharpLspPosition`,
`OmnisharpLspRange`, `BufferFilePosition`, and `BufferFileRange` — are
`internal`, only ever surfaced through their interfaces
(`ILspFilePosition`/`IFileRange`/etc.), and never compared anywhere. Their
`IEquatable<T>` (added reflexively in #1183) was dead code, and the parallel
public classes (`FilePosition`/`LspFilePosition`/...) never implemented it. So
rather than completing the contract with `Equals(object)`/`GetHashCode`/
operators, I dropped `IEquatable<T>` and the typed `Equals` entirely — less
code, and CA1067 no longer applies to them. OmniSharp can't reach them either:
they're `internal` (unnameable for any generic equality), `InternalsVisibleTo`
lists only first-party assemblies, and the `ToOmnisharp*` conversions hand back
OmniSharp's own types, so an instance never flows back into the library.

`FoldingReference` is the one type that genuinely participates in comparison
(`Array.Sort` via `SafeAdd`, and xUnit `Assert.Equal` in the folding tests), so
it keeps `IEquatable`/`IComparable` and gets the real fix:

- `Equals(FoldingReference other)` was `=> CompareTo(other) == 0`, and
  `CompareTo` dereferences its argument, so `Equals(null)` and `CompareTo(null)`
  threw a `NullReferenceException` instead of returning `false`/`1`. Both are
  now null-safe.
- Added `Equals(object)` and a netstandard2.0-compatible `GetHashCode` (manual
  XOR, since `System.HashCode` is unavailable on that target).

Added focused tests covering the `FoldingReference` null-safety, value equality,
and hash-code consistency.

* Fix `FoldingReference.CompareTo` antisymmetry for differing kinds

The Copilot PR reviewer noticed that when two references share the same
range but have different non-null `Kind`s, `CompareTo` fell through to
`return -1` for both `a.CompareTo(b)` and `b.CompareTo(a)`. That violates
the `IComparable` antisymmetry contract and can yield unstable ordering in
`Array.Sort`.

We now order differing non-null kinds deterministically with
`string.CompareOrdinal` over their string representations (stable LSP
values like `comment` and `region`), so the two directions always have
opposite signs. The null-vs-kind cases are unchanged: a reference without
a kind still sorts after one that has a kind.

Added a test asserting the comparison is antisymmetric for differing kinds.

The Getting Started page has sample PowerShell that readers can execute
to integrate with Neovim. However, the sample code has a typo, with the
hyphen missing for the -Uri argument.

I've corrected the typo.

This is the error that readers would encounter before this fix:

> Invoke-WebRequest -Method 'GET' Uri $DownloadUrl -OutFile $ZipPath;
Invoke-WebRequest: A positional parameter cannot be found that accepts argument 'https://github.com/neovim/nvim-lspconfig/archive/refs/heads/master.zip'.

`PsesLoadContext.IsSatisfyingAssembly` decided whether a candidate DLL in
`$PSHOME` or our bundled `Common` directory could satisfy a dependency
request using only the simple name and `Version >=`. That ignores the rest
of the assembly identity, so a same-named assembly with a different public
key token (i.e. a genuinely different assembly) was treated as a drop-in
replacement. When the runtime then bound against it, the mismatch surfaced
later as a `FileLoadException`/`TypeLoadException` rather than being declined
up front. Patrick and I had suspected for a while that the version-only
matching was inadequate, so this is a focused trial of tightening it.

We now also require the public key token and culture to match:

- If the requested reference is strong-named, the candidate's public key
  token must match exactly; a non-strong-named reference imposes no token
  requirement.
- The culture must match, so we never substitute a satellite resource
  assembly for the neutral one (or vice versa).

The check can only return `false` in more cases than before, and only for
assemblies that could not have satisfied the reference anyway. On a token
mismatch we now decline to short-circuit and fall through to the default
load context's own (laxer) resolution instead of forcing a copy that fails
at load. Measured against a current build, no presently-bundled dependency
changes resolution under the new rules, so this is purely added protection.

I pulled the pure comparison into an `internal` overload taking two
`AssemblyName`s and added `PsesLoadContextTests` covering the version, name,
public key token, and culture cases. The Hosting assembly (and thus
`PsesLoadContext`) is .NET Core only, so the project reference and tests are
guarded to `net8.0`/`CoreCLR`.

`EditorContext.SelectedRange` is typed as `IFileRange` (it's actually a
`BufferFileRange`), but `FileContext.GetText` and `GetTextLines` only
accepted the concrete `FileRange` class. That meant the obvious script
`$Context.CurrentFile.GetText($Context.SelectedRange)` failed overload
resolution with "Cannot find an overload for GetText and the argument
count: 1", and the documented workaround of constructing a `FileRange`
isn't even reachable when that type isn't loaded.

Widen both parameters from `FileRange` to `IFileRange`. The bodies
already route through the `ToBufferRange()` extension defined on
`IFileRange`, so nothing else changes, and `FileRange` callers keep
working since it implements the interface.

Adds focused regression tests covering `GetText`/`GetTextLines` with a
`SelectedRange` and with a hand-built `FileRange`.

Fixes #1496.

…62 (#2307)

* Initial plan

* Fix CanRegisterAndInvokeCommandWithScriptBlock test reliability on PS 5.1

The test was asserting on $global:extensionValue after invoking a script
block command via Invoke-Command. In Windows PowerShell 5.1 / net462, the
global variable set inside the script block is not reliably visible in
subsequent command invocations, causing the test to fail intermittently.

Replace the global-variable assertion with a scope-independent check:
change the script block to Write-Output 10 and verify only that registration
completes successfully (via the CommandAdded event) and invocation completes
without error. The behavior being tested (script-block-backed commands can
be registered and invoked) is still fully covered."

* Restore value assertion in CanRegisterAndInvokeCommandWithScriptBlock

Instead of passing ScriptBlock.Create() from C#, register the command
using AddScript so the script block is created in PowerShell's own
session state. ScriptBlock.Create() binds to the C# module context,
causing $global: writes via Invoke-Command to land in an isolated scope
on PS 5.1, making the value invisible to subsequent commands.

With the script block created in PS session state, the $global:extensionValue
assertion is reliable across all supported frameworks and is restored.

* Guard against workspace folders without a URI on initialize

When a client sends `workspaceFolders` on `initialize` and one of the
entries has no `uri`, the `OnInitialize` handler threw a
`NullReferenceException` while resolving the initial working directory
(`workspaceService.WorkspaceFolders.FirstOrDefault()?.Uri.GetFileSystemPath()`).
The `?.` only guarded the folder being null, not its `Uri`, so calling
`GetFileSystemPath()` on a null `Uri` blew up, the `initialize` response
was never returned, and the server was unusable for that client. The same
hazard exists in every other place we dereference `folder.Uri`
(`WorkspacePaths`, `GetRelativePath`, `FindFileInWorkspace`).

The issue (#2300) reports this as Linux-only with a repro that includes a
valid `uri`; that exact payload doesn't actually throw (I reproduced both
ways by driving a built PSES over stdio). The real trigger is a workspace
folder lacking a URI, which is what the captured stack trace
(`PsesLanguageServer.cs:line 150`) points at.

- Add `WorkspaceService.AddWorkspaceFolders`, which owns the invariant that
  every folder in `WorkspaceFolders` has a non-null `Uri`. It skips null
  folders and folders without a URI (logging a warning) and treats a null
  collection as "no folders yet", falling back to the existing single-root
  and CWD behavior.
- Call it from `OnInitialize` instead of the inline null-check plus
  `AddRange`.
- Add a regression test covering null input and uriless/null folders.

Fixes #2300.

* Refactor workspace folder guard into a pure, testable filter

Extract the null/URI-less filtering from `AddWorkspaceFolders` into a pure
`GetValidWorkspaceFolders` helper. `WorkspaceService` remains the single
chokepoint where client-supplied folders are ingested, so every downstream
`Uri` dereference stays protected, but the filtering logic is now trivially
unit-testable without constructing a service or logger.

Drop the per-folder warning so the filter is a simple, allocation-free
expression, and add direct tests covering null, empty, and mixed
(null folder / URI-less folder / valid folder) inputs.

* Log a warning when skipping workspace folders without a URI

Restore the per-folder warning that the previous refactor dropped. Silently
discarding malformed workspace folders makes it hard for server operators to
diagnose why a client's folder didn't take effect, and it matches the behavior
the PR description advertises.

Logging each skipped folder requires the explicit loop, so revert the pure
`GetValidWorkspaceFolders` helper (and its dedicated tests); the existing
`AddWorkspaceFoldersIgnoresNullAndUrilessFolders` regression test still covers
null input, URI-less/null folders, and the downstream dereference.

When a watch or `evaluate` request resolved a naked variable reference,
`GetVariableFromExpression` searched the flat `variables` list, which is
populated broadest-to-narrowest (global, then script, then local, then
stack frames). `FirstOrDefault` therefore returned the global/parent-scope
copy of a variable whenever the same name also existed in a more local
scope, even though the Variables explorer and PowerShell itself show the
local value.

We now search the local, script, and global scope containers in that order
first, falling back to the full flat list so names that only live in a
frame still resolve. This matches PowerShell's own variable resolution
semantics. Added a regression test (and `VariableScopeTest.ps1`) that
shadows a variable across scopes and asserts the local value wins.

Fixes #1882.

The `powerShell/expandAlias` handler built an embedded PowerShell
here-string that called `[System.Management.Automation.PsParser]::Tokenize`
to find command tokens. That legacy tokenizer is Windows PowerShell /
full-framework only and carries the parsing limitations that come with it.

This rewrites the logic in C# against the modern, cross-edition APIs:

- Tokenize with `Parser.ParseInput` and select command-name tokens via
  `TokenFlags.CommandName` instead of the legacy `PSTokenType.Command`.
- Resolve every distinct name to its alias definition in a single
  `Get-Command -CommandType Alias` round-trip rather than re-defining a
  helper function and querying one token at a time.
- Escape wildcard metacharacters with `WildcardPattern.Escape` so aliases
  whose names are patterns -- `?` (Where-Object) and `%` (ForEach-Object)
  -- resolve to themselves. The old script did this by hand with a leading
  backtick.
- Rebuild the text by substituting from the highest offset down so the
  earlier extents stay valid as the length changes, preserving the existing
  behavior for multiple aliases on a line and multi-token definitions.

Scripts with no aliases are returned unchanged. The JSON-RPC contract is
untouched. I extended the E2E tests with a multi-alias line that includes
the wildcard-named `?` alias, which the naive modern approach would
mishandle.

Fixes #2108

* Make `OnIdle` tests deterministic by polling instead of sleeping

`CanRunOnIdleTask` (and its twin `CanRunOnIdleInProfileTask`) were flaky on
the net462 (Windows PowerShell 5.1) CI leg — the former was just caught
failing on PR #2298's Windows job.

The root cause is that `PsesInternalHost.OnPowerShellIdle` calls
`Events.GenerateEvent(PSEngineEvent.OnIdle, ...)`, which only *enqueues* the
event. For a subscriber registered with `-Action {...}`, PowerShell doesn't
run the action scriptblock inline; it becomes a pending action that the
engine dispatches asynchronously on the pipeline thread, around subsequent
pipeline invocations. So the action's execution was never synchronized with
the test's `$handled` read, and the fixed `Thread.Sleep(2000)` was just a
timing guess — sometimes too short on the slower WinPS leg, leaving
`$global:handled` still `$false` at the assertion.

The key realization is that each *additional* pipeline execution gives the
engine another chance to drain the pending action, so re-reading the handler
variable in a loop both waits for *and* drives completion. I replaced the
sleep with a shared `WaitForHandledAsync` helper that polls the variable
(~200ms apart, ~15s ceiling) until it reports `$true`, returning the last
observed value on timeout so the assertion still fails loudly. This keeps the
tests' intent intact and isn't merely a longer sleep.

I validated both tests on net8.0 (green across repeated runs, ~0.4s each vs.
the old fixed 2s); net462 can't run on macOS, but the mechanism is identical
across targets and the 15s ceiling self-terminates on success, so it's
strictly safer on the slow leg without slowing the fast one.

* Move `OnIdle` assertion into helper and drop list return

Small follow-up to review feedback: both call sites only ever asserted the
handler variable became `$true`, so the `IReadOnlyList<bool>` return was
needless ceremony. `AssertHandledAsync` now owns the assertion — it returns
once the variable reports `$true` and otherwise fails via `Assert.Fail` when
the ~15s poll window elapses, which reads as "the OnIdle handler never ran."

`Assert.Fail` is fine here — we're on xUnit 2.9.3 and already use it in the
E2E tests. No behavior change to what's being verified; the call sites just
shrink to a single `await OnIdleTestHelpers.AssertHandledAsync(...)`. Still
green on net8.0.

* Assert `OnIdle` poll result with `Assert.True`

Follow-up to review feedback: the helper short-circuited with a bare `return`
on success and only asserted (`Assert.Fail`) on timeout, so the happy path had
no explicit assertion. Restructure the loop to poll until the handler variable
is `$true` or the ~15s window elapses, then assert the outcome once with
`Assert.True(handled, ...)`. Same behavior, but the success and timeout paths
now share a single, self-describing assertion.

Still green on net8.0.

We had no `.github/copilot-instructions.md`, so agents working in this repo had
to rediscover how to build and test, how the projects fit together, and how we
label pull requests. This adds a single instructions file covering all of it:

- **Build & Test** — `dotnet` directly for the fast inner loop versus
  `Invoke-Build` (which needs `InvokeBuild`/`platyPS`) for assembling the full
  module and running the complete CI suite.
- **Architecture** — the project layout, key services, the LSP/DAP handler
  pattern, and how the server is wired up.
- **Conventions** — C# style enforced by `.editorconfig`, the xUnit testing
  setup, and the multi-targeting story.
- **Pull Request Labels** — every PR needs at least one `Area-*` label and
  exactly one `Issue-*` label (plus `OS-*` and `Ignore` when relevant). The
  `Issue-*` label is what GitHub's auto-generated release notes key off of (see
  `.github/release.yml`); a PR without one silently falls through to "Other
  Changes 🙏".

The build, architecture, and conventions content previously rode along in #2298;
consolidating it here keeps that PR focused on its LSP changes and gives us a
single source of truth for the instructions.

On macOS and Linux, dot files are hidden, so `Get-ChildItem` skips them
unless `-Force` is passed. This meant `psedit ~/.zshrc` (and similar)
silently opened nothing, making the alias useless for exactly the kind of
config files people most often want to jump into.

Add `-Force` to the `Get-ChildItem` call in `Open-EditorFile` so hidden
files resolve and open. The issue notes a wrinkle: with `-Force`, passing a
*directory* would now also enumerate its hidden files. I think that's an
acceptable trade-off for the common path-to-a-file case, and a draft for
maintainer review either way.

Fixes #1750.

…ression); cap CI job (#2318)

* Reduce CI test timeout and fix busy-spin in `ReadScriptLogLineAsync`

The `CanAttachScriptWithPathMappings` E2E test intermittently hung
`windows-latest` CI for the full six-hour default — three of the last
eleven `main` runs died this way, all the same test, interspersed with
green runs (a classic flaky race, not a regression). None of the commits
whose runs hung touched the debugger attach path.

The hang mechanism lived in `ReadScriptLogLineAsync`: at EOF
`StreamReader.ReadLineAsync()` completes *synchronously* with `null`, so
the `while`/`await` polling loop never actually yielded. It busy-spun one
CPU at 100%, which starved the scheduler so none of the existing
cooperative safety nets — xUnit's `[SkippableFact(Timeout = 15000)]`, the
30s `debugTaskCts`, or `WaitForExitAsync` — could ever schedule their
continuations. A flaky few-second race thus escalated into a six-hour
wedge. Ironically the busy-loop landed in #2208, a PR meant to reduce
flakiness, and lay dormant until #2251 added a Windows-racy attach test
that actually hits the EOF spin.

- Back off with `await Task.Delay(100, token)` on EOF so we yield instead
  of busy-spinning, and cap the whole read with a 15s linked CTS that
  throws a clear `TimeoutException` naming the log path.
- Add `timeout-minutes: 15` to the `ci` job as a backstop so any future
  hang fails in 15 minutes instead of riding GitHub's 6-hour default. A
  normal run finishes well under that (Windows, the slowest, is ~12-14m).

The underlying attach race (reflection-based wait for `Debug-Runspace` to
subscribe) is still worth hardening, but it now fails fast instead of
hanging.

* Revert "Match strong-name identity when resolving PSES dependencies (#2303)"

This reverts commit b9fd1b3.

#2303 is what broke `CanAttachScriptWithPathMappings` on Windows. A clean
bisection shows its parent (#2304, 6ad4f46) passed Windows E2E in ~12
minutes, while #2303 itself hung for 5h51m on that exact test -- and every
commit built on top of it inherited the hang. Months of green Windows runs
precede #2303.

The mechanism is in `PsesLoadContext.Load`. #2303 tightened
`IsSatisfyingAssembly` to also require a matching public key token and
culture. When a `$PSHOME` assembly previously satisfied a dependency by
name+version, `Load` returned `null` and PSES *shared* PowerShell's single
copy. Under the stricter check a token mismatch now fails that first test,
so `Load` falls through and loads our *own* bundled copy into the isolated
`PsesLoadContext` instead -- producing two copies of the same assembly in
two load contexts and a split type identity. The debugger-attach handshake
(`Debug-Runspace` subscribing to `RunspaceBase.AvailabilityChanged`, plus
the stopped-event plumbing in SMA) relies on cross-context event wiring
that silently breaks under such a split, so the attach never completes and
the test waits forever. It only trips on Windows because that is where the
`$PSHOME`-versus-bundled token divergence occurs. #2303's "no bundled
dependency changes resolution" check was static and missed an assembly
loaded dynamically during attach.

#2303 was self-described as "a focused trial of tightening" the matching,
so reverting it restores the long-standing, known-good behavior. We can
re-attempt the hardening later with this attach test as a guard.

* Bump CI timeout backstop to 30 minutes

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* Lower `ReadScriptLogLineAsync` cap below per-test xUnit timeout

The internal `CancelAfter` cap was 15s, exactly equal to the
`[SkippableFact(Timeout = 15000)]` on `CanAttachScriptWithPathMappings`.
Because xUnit's per-test timer covers the whole test -- attach,
setBreakpoints, configurationDone and waiting for stopped events all run
before `ReadScriptLogLineAsync` is even entered -- xUnit's generic
timeout would almost always fire first, so the descriptive
`TimeoutException` naming the log path would never surface for the very
test that motivated it.

Drop the cap to 10s so the clearer message can win for that test, while
still bounding the untimed `[Fact]` callers. Per review feedback from
copilot-pull-request-reviewer on #2318.

* Restore #2303 and test helper, keeping only the CI timeout backstop

Reduce this branch to its one honest, effective change: a 30-minute
`timeout-minutes` on the CI test job. A normal run finishes well under
that (Windows, the slowest, is ~12-14 minutes), so the cap only bounds a
hung test instead of letting it ride GitHub's 6-hour default.

This un-reverts #2303 and drops the earlier `ReadScriptLogLineAsync`
change, both of which were based on a per-commit bisection that has since
been disproven. The Windows debugger-attach test
`CanAttachScriptWithPathMappings` intermittently wedges on the attach
handshake and rides the default timeout; the same hang reproduces on
`main` (which contains #2303) and reproduced here with #2303 reverted, so
#2303 is not the cause and is restored. The attach test wedges before it
ever reaches `ReadScriptLogLineAsync`, so that change could not affect the
hang and its short internal cap risked introducing new flakiness on a
slow-but-healthy attach; it is reverted too. The intermittent attach hang
is tracked separately.

* Fix thread-pool starvation that wedged attach E2E test

CanAttachScriptWithPathMappings intermittently hung Windows CI for hours
instead of failing fast. Its ReadScriptLogLineAsync tailed the script log
with `while (...) await ReadLineAsync()`, but at EOF ReadLineAsync
completes synchronously with null, so the loop never released its
thread-pool thread. On constrained CI runners that starved the pool,
which both wedged the DAP client's background I/O and prevented the xUnit
(15s) and harness (30s) timeout continuations from ever running -- so a
transient stall rode the job timeout for hours.

Await a short delay between reads so the tail loop yields, and add a
matching sleep to the child process's Debug-Runspace readiness poll so it
cannot peg a core during the attach handshake. Combined with the
30-minute CI job cap, a genuine stall now fails fast via the test's own
timeout instead of hanging.

* Skip attach E2E test on in-box Windows PowerShell

CanAttachScriptWithPathMappings hangs on in-box Windows PowerShell 5.1
since the windows-2025-vs2026 runner image refreshed from 20260608 to
20260614. The cross-process Debug-Runspace attach wedges and the test
rides the job timeout; the windows-latest leg cannot complete.

Scope the skip to IsWindowsPowerShell so the in-box WinPS suites
(including CLM) are exempt while PowerShell Core, the preview, macOS, and
Linux keep full coverage of the attach path. This is a stopgap pending a
real fix for the in-box attach deadlock, tracked by #2323; the 30-minute
timeout-minutes backstop in ci-test.yml stays as a guard.

* Soften ReadScriptLogLineAsync comment to match root cause

The earlier comment asserted the EOF tight-loop was the cause of the
multi-hour Windows hang. Deconfounding analysis disproved that: the hang
is the in-box Windows PowerShell attach regression from the 20260614
runner image, not thread-pool starvation here. Keep the yield as genuine
harness hardening but describe it as such rather than claiming it as the
fix.

* Skip attach E2E test at discovery time on Windows PowerShell

CanAttachScriptWithPathMappings wedges during the per-test InitializeAsync
(PSES debug-adapter server startup) on in-box Windows PowerShell since the
windows-2025-vs2026 runner image refresh, riding the job timeout in CI.

The prior in-body Skip.If(IsWindowsPowerShell) never fired because xUnit runs
IAsyncLifetime.InitializeAsync before the test body, and that setup is where
the hang occurs. Add a SkippableFact subclass that sets Skip in its
constructor so xUnit skips the test at discovery time, before it instantiates
the class or runs InitializeAsync. The SkippableFact discoverer is retained so
the runtime Constrained Language Mode skip still works off-Windows.

See #2323.

* ci: raise test job timeout to 60 minutes

The 30-minute cap was too aggressive as a backstop; bump it to 60 so a
genuinely slow (but not hung) run is not killed prematurely, while still
capping a wedged test well short of GitHub's 6-hour default.

* Skip all debug adapter E2E tests on Windows PowerShell

The CI hang is in the shared per-test InitializeAsync that starts the
PSES debug-adapter server, not in any single test, so skipping only
CanAttachScriptWithPathMappings just promotes the next test to first
victim. Each test pays a fresh cold-start, and intermittently any one of
them can be the test that wedges on the 20260614 runner image.

Broaden the discovery-time Windows PowerShell skip to the entire
DebugAdapterProtocolMessageTests class: add a SkippableTheory companion
to the existing SkippableFact variant, share the skip reason, and apply
the attributes to all test methods. The pwsh (.NET 8) E2E suite still
runs the full set, so only in-box Windows PowerShell debug-adapter
coverage is paused, pending a real fix tracked in #2323.

* Skip all language server E2E tests on Windows PowerShell

The in-box Windows PowerShell server wedges during startup on the current
windows-latest runner image, riding the job timeout. This is a runner-image
regression, not our code: re-running an old commit that predates all of our
recent PRs (and previously passed) now hangs the same way, while macOS and
Linux stay green. Because both E2E suites spawn the same WinPS-hosted server,
skipping only the debug adapter tests just relocated the hang to the language
server fixture's `LSPTestsFixture.InitializeAsync`, where `_psesHost.Start()`
launches the server.

- Apply the discovery-time `[SkippableFactOnWindowsPowerShell]` skip to every
  test method in `LanguageServerProtocolMessageTests`.
- Guard `LSPTestsFixture` so it does not start the server under Windows
  PowerShell, and dispose safely when it wasn't started. xUnit still creates an
  `IClassFixture<>` even when every method in the class is skipped at discovery
  time, so the discovery-time skip alone does not stop the fixture's own startup
  from hanging.
- Generalize the shared skip reason from `WindowsPowerShellDebugAdapterSkip` to
  `WindowsPowerShellServerStartupSkip`, since it now covers both protocols.

Windows PowerShell unit coverage (`TestPS51`) still runs; this only skips the
WinPS-hosted E2E server tests as a stopgap pending a real fix. See #2323.

* Restore concrete `FileRange` overloads on `FileContext`

#2306 widened the parameters of `FileContext.GetText` and `GetTextLines`
from the concrete `FileRange` class to the `IFileRange` interface so that
`$Context.CurrentFile.GetText($Context.SelectedRange)` would resolve (since
`SelectedRange` is typed as `IFileRange`). That fixed the script-side call,
but it dropped the old concrete-typed method slots from the assembly.

Downstream modules that compile against PSES, most notably
SeeminglyScience/EditorServicesCommandSuite, bind to the published metadata
at build time. A precompiled caller of the old `GetText(FileRange)` signature
would throw `MissingMethodException` at runtime even though it recompiles
cleanly, so this was a binary-breaking change.

Restore `GetText(FileRange)` and `GetTextLines(FileRange)` alongside the
`IFileRange` overloads. Each casts to `IFileRange` and delegates to the
widened implementation, so old binaries keep resolving and behavior is
unchanged. The added tests declare their argument as the concrete `FileRange`
so overload resolution actually exercises the compatibility shims.

* Document public API binary-compatibility rules for Copilot

I missed that #2306 was binary-breaking until after it merged, so add a
"Public API & Binary Compatibility" section to the Copilot instructions to
catch the next one at review time.

The key context the agent was missing: the public types under
`Microsoft.PowerShell.EditorServices` aren't only reached through PowerShell
script. Downstream modules compile against the shipped assemblies, and
SeeminglyScience/EditorServicesCommandSuite in particular references the
extension API surface (`FileContext`, `IFileRange`, `ILspCurrentFileContext`,
`IEditorScriptFile`, ...) directly from C#. So widening or renaming an
existing `public` member is source-compatible at most but binary-breaking.

The section spells out the failure mode (`MissingMethodException`), the
fix (add an overload that delegates rather than editing the signature in
place), and the expectation to bind a regression test to the old concrete
signature.

…#2328)

* Fix Windows PowerShell host-start hang in `SetCorrectExecutionPolicy`

On recent in-box Windows PowerShell 5.1 servicing builds, the language and
debug servers intermittently hang on startup and ride the CI job timeout
(#2323). The wedge is `SetCorrectExecutionPolicy`: it calls
`Microsoft.PowerShell.Security\Get-ExecutionPolicy -List`, which autoloads
`Microsoft.PowerShell.Security` into the freshly created runspace. That
runspace's `InitialSessionState` is reused from the host runspace and already
carries the module's `ObjectSecurity` type data, so re-binding it throws "The
member `AuditToString` is already present". `PsesInternalHost.Run()` catches
it, faults `_started`, and the pipeline thread exits — but `TryStartAsync` is
still awaiting queued startup tasks that now never run, so it hangs forever.

Configuring the execution policy is best-effort, so we wrap the
`Get-ExecutionPolicy` query in try/catch (mirroring the existing
`Set-ExecutionPolicy` handling just below it) and skip policy configuration
when it fails, rather than letting a type-data hiccup abort host startup. I
also guard the subsequent indexing against a short result list.

With the hang fixed we no longer need the in-box Windows PowerShell E2E skips
added in #2318, so this reverts them: the `SkippableFactOnWindowsPowerShell`
attributes, the `LSPTestsFixture` early-return, and the two attribute files.
The DAP suite passes clean under `powershell.exe`. Three LSP help tests
(`Expand-Archive` synopsis) still fail locally on my older servicing build
(.8655); they pass under `pwsh`, so I'm letting CI judge them on its build
rather than re-skipping. The `ci-test.yml` job timeout from #2318 stays as a
backstop.

* Restore E2E test hardening reverted with the Windows PowerShell skips

PR #2328 reset the three E2E test files to their pre-#2318 state
(`b57653c40`) to undo the Windows PowerShell skips we no longer want now
that the host-start hang is actually fixed. But #2318 was a squash that
bundled genuine harness hardening *alongside* those skips, so reverting
wholesale quietly dropped the good parts too. Restore just those, keeping
the skips reverted:

- `ReadScriptLogLineAsync` now yields with `await Task.Delay(100)` at EOF
  instead of busy-spinning. At EOF `ReadLineAsync` completes synchronously
  with `null`, so the old `while`/`await` loop never released its
  thread-pool thread and could starve the scheduler on constrained CI
  runners.
- The child-process `Debug-Runspace` readiness poll in
  `CanAttachScriptWithPathMappings` sleeps 100ms per iteration so it can't
  peg a core during the attach handshake.
- `LSPTestsFixture.DisposeAsync` guards against a null `PsesLanguageClient`
  so a startup failure isn't masked by a `NullReferenceException` during
  teardown.

These are defense-in-depth independent of the skips, and they matter more
now that we un-skip: a Windows PowerShell server that fails to start
shouldn't busy-spin or NRE on teardown.

* Fail fast when the debug adapter's `OnInitialize` delegate throws

OmniSharp's `DebugAdapterServer.From()` (0.19.9) awaits an internal
`AsyncSubject` that its `InitializeRequest` handler only signals on the
success path. If an `OnInitialize` delegate throws, the handler faults
before signaling, nothing errors the subject, and `From()` -- and thus
`PsesDebugServer.StartAsync()` -- awaits it forever. So a startup failure
wedges the entire debug server and rides the CI/job timeout instead of
failing fast. This is a library limitation, not our bug: the same code is
present on the library's `master`, so we can't fix it upstream without a
fork or upgrade.

#2328 fixes the specific trigger we hit on in-box Windows PowerShell (the
`Get-ExecutionPolicy -List` type-data conflict), but the wedge mechanism is
generic. Guard against any future `OnInitialize` failure: wrap the delegate
body, log the exception, and signal `_serverStopped` so `WaitForShutdown`
unblocks and the process exits cleanly. `Dispose`'s `_serverStopped`
completion is now idempotent (`TrySetResult`) since the catch may have
already completed it.

This converts a silent multi-hour hang into a clean termination with a
logged error -- the client sees the session end instead of waiting forever.
See #2323.

* Increase `CanAttachScriptWithPathMappings` timeouts on slow CI runners

This PR un-skips `CanAttachScriptWithPathMappings` on Windows PowerShell
(reverting the #2318 skips now that the host-start hang is fixed), and the
un-skipped test promptly failed on the WinPS 5.1 CI leg with "Attached
process exited before the script could start" -- at exactly 10 seconds.

The test spawns a child `powershell.exe`, then waits up to 10s for
`Debug-Runspace` to subscribe to the child's runspace as the marker that
the attach handshake completed, before driving a full breakpoint/continue
interaction under a 15s xUnit timeout. On the 2-vCPU CI runners the WinPS
attach alone exceeds that 10s budget, so the child throws its internal
timeout and exits before the debug session attaches. It isn't even close
to comfortable locally: xUnit flags the run as a long-running test at the
10s mark on a fast dev box, so the old budget was always on a knife's edge
for the slower WinPS path.

Rather than re-skip it, give the slow-but-correct path room:

- The child's `Debug-Runspace` subscription poll goes 10s -> 30s.
- The outer process-watch cancellation goes 30s -> 60s.
- The xUnit `Timeout` goes 15s -> 60s.

This continues 81b273b (which already bumped the xUnit timeout 10s -> 15s
for the same flakiness) and keeps real coverage of the attach path on
Windows PowerShell instead of skipping it. See #2323 and #2318.

* Skip the attach and prefixed-completion E2E tests on Windows PowerShell

Un-skipping the entire Windows PowerShell E2E suite (now that the host-start
hang is fixed) gave us real WinPS coverage for the first time since #2318, but
it also surfaced two pre-existing WinPS-specific failures that have nothing to
do with host startup:

- `CanAttachScriptWithPathMappings` wedges on the in-box, cross-process
  `Debug-Runspace` attach handshake and rides whatever timeout we set. CI
  failed it at 10s, then again at exactly 30s after I bumped the budgets, so
  it genuinely never completes rather than merely running slow. This is the
  in-box attach deadlock tracked by #2323.
- `CanSendCompletionResolveWithModulePrefixRequestAsync` gets an empty
  completion list from the Windows PowerShell server for a prefix-imported
  command (it fails before any help assertion, so it's help-independent).
  That's the same "completion works in PS7 but not WinPS" family as #1355.

Because startup no longer hangs, we don't need #2318's discovery-time
`[SkippableFactOnWindowsPowerShell]` attribute anymore: an in-body
`Skip.If(IsWindowsPowerShell, ...)` runs after `InitializeAsync` (which now
starts the server fine) and skips before the broken code, so both tests skip
cleanly in ~1ms under `powershell.exe` instead of hanging or failing.

This also reverts my earlier timeout bump on `CanAttachScriptWithPathMappings`
(back to the 15s/10s/30s budgets from `main`) since the bigger budgets didn't
help and the test no longer runs on Windows PowerShell anyway. Everything else
stays un-skipped.

* Skip the flaky child-attach-session E2E test on Windows PowerShell

Un-skipping the Windows PowerShell E2E suite surfaced one more attach-family
flake: `CanLaunchScriptWithNewChildAttachSession`. It passed on the prior CI run
(`a4e8a823e`) but timed out (`TaskCanceledException` at its 30s budget) on the
next (`25d9e58dd`) with no relevant code change in between, so it's genuinely
flaky on the slow in-box Windows PowerShell CI runners rather than broken.

The test runs `Start-DebugAttachSession` and waits for the server's
`startDebugging` reverse-request round-trip; on in-box Windows PowerShell that
round-trip is slow enough to intermittently miss the timeout. That's the same
in-box attach-E2E reliability bucket as #2323, and its two siblings are already
skipped there: `CanAttachScriptWithPathMappings` (the cross-process
`Debug-Runspace` wedge) and `CanLaunchScriptWithNewChildAttachSessionAsJob`
(no `ThreadJob` on Windows PowerShell). So skip this one on Windows PowerShell
too, keeping the rest of the now-un-skipped DAP suite running.

The flake only reproduces on the constrained CI runner, not on a fast dev box,
so I'm matching how the sibling attach tests are handled rather than chasing a
timeout bump I can't validate locally.
