feat(fleet): cover agentic consumers and fail on uncovered ones

[hseshadr]

Claim touched: the fleet scan covers every repository that consumes hseshadr/ci Dagger modules.

Why

The fleet scan only checked repositories listed by hand in repository_expectations. agentic-saga and agentic-context-service both pin github.com/hseshadr/ci/modules/*, but neither was listed. So no fleet rule ran on them: not the pin floor, not the pin format, nothing.

What

• Both repos are added to repository_expectations with the full consumer contract: sole Dagger check, conversation resolution, no linear-history requirement, no rollout exception. Both already declare shared foundation, which is why there is no grandfather date. The values come from their live dagger.json and branch protection.
• New .dagger/src/ci/fleet_coverage.py. Each hosted scan lists every public hseshadr repo (users/hseshadr/repos, paginated) and reads its default-branch dagger.json. Any active repo that pins a github.com/hseshadr/ci module but is not in the list gets an uncovered-consumer finding, and the scan fails. If the listing or a config read fails with anything other than a 404, the scan fails closed.
• scan_repository now turns a FleetAccessError into an evidence-unreadable finding. Before this, one unreadable repo aborted the whole scan and hid every result after it. The scan still fails.
• Docs: the docs/dagger-modules.md#fleet-coverage section, plus README and CHANGELOG.

This touches fleet.py and adds new files only. It does not touch fleet_policy.py or github_fleet.py, so there is no textual overlap with #47. I merged it with feat/fleet-minimum-pin locally: 245 passed, poe gate exit 0.

Evidence

Check	Result
RED (guard)	test_should_cover_every_known_ci_consumer_in_reviewed_expectations: Left contains 2 more items, first extra item: 'agentic-context-service'. The consumer-set test and both expectation tests were also red.
GREEN	uv run poe gate exit 0: 231 passed, fleet.py and fleet_coverage.py at 100% line and branch coverage, xenon A
M1: drop agentic-saga from expectations	3 red
M2: scan skips coverage results	1 red (hosted-scan wiring test)
M3: fail open on an unreadable dagger.json	1 red
M4: include archived repos	2 red
M5: stop after the first listing page	1 red
M6: match only hseshadr/ci@ and miss module-path pins	3 red
M7: abort the scan on an unreadable repo	2 red
Live discovery (read-only)	exactly agentic-context-service, agentic-saga, almamesh, aml-filter, assay, edge-proc, edge-reco, edgeproc-core, privacy-core, which equals KNOWN_CONSUMERS

New live findings this surfaces (intended, the scan is meant to fail on them)

Repo	Code	Detail
agentic-context-service	evidence-unreadable	branches/main/protection returns 404: main has no branch protection or ruleset at all
agentic-saga	explicit-source	source is a caller-supplied ci(source=...) argument, not a module-owned Directory field built from Workspace or DefaultPath

Both are consumer-side fixes. They are tracked separately and are not changed here. The scheduled Dagger fleet policy run is already red on main because of edge-proc, edgeproc-core and privacy-core.
