…ue (RIG-2883)
T1 of the board-ingestion forge poll→webhook cutover: `BoardWebhookArm`, a second consumer behind the one GitHub ingress.
`Enqueue` satisfies `server.ForgeEventSink`'s non-blocking contract — it filters to board-relevant issue events (`Change ∈ {OPENED, STATE, UPDATE} ∧ Kind == ISSUE`; PR-kind and COMMENT-change dropped) then channel try-sends; a full queue DROPS the event with an exported `expvar` drop metric + Warn (the T3 reconciler heals it).
`Run` drains until ctx cancel (returns nil, driver.go:95-99 idiom). Each drain COALESCES per NORMALIZED `(repo, number)` coordinate first, so an N-event edit storm on one issue costs ONE hydrate GET. Per coordinate: lowercase the event repo (Global Constraint 8), `IsEnabledRepo` gate, unconditional `GetIssueConditional(repo, number, "")`, then `IngestIssues` through the shared owner-strip/translate/stamp pipeline. Per-event errors log-and-continue; `ErrBudgetExhausted` pauses the drain until the client gate reopens.
Interfaces (`issueHydrator`, `TargetChecker`) are defined LOCALLY — structural seams the concrete `*forge.GitHub` and `*store.Store` satisfy at T5 wiring; this package imports no store and no concrete forge client on the hydrate path.
