Drop unused AppleEvents usage string; de-stale Phase-N comments

The NSAppleEventsUsageDescription usage string was dead — the app has no AppleEvents/AppleScript code path (Meet detection reads window titles), so the permission prompt never fired; remove it. Rephrase the leftover "Phase N" build-plan references in source comments (one of which falsely claimed "no audio, capture, or call detection yet"), and complete the AGENTS.md Audio/Detection layout listings.

 ## Quality / debt (from the 2026-06-13 independent eval — full queue + evidence in `EVALUATION.md`)
 - Guard `RecapAnalyzer.mmss()` (`:137`) against NaN/∞ — a malformed backend `duration` aborts the app at recap render (eval P2). Cheap; fold into the next backend change.
 - Add `SessionController` state-machine tests (`pendingAutoStop`, visual-adoption generation guard) before refactoring; then extract its saved-session / open-panel UI (eval P2/P3).
-- Optional: sweep the stale "Phase N" references in source comments (e.g. `SparkControlHealth.swift:7` "arrives in Phase 5", `Ten31TranscriptsApp.swift:6` "Phase 0 only") — historical, not false, but dated. `docs/04_BUILD_PLAN.md` is now marked COMPLETE/historical and is the map for these.
-- Smaller P3s in `EVALUATION.md`: incomplete AGENTS Layout listings, unwritten `manifest.json` sha256 contract (now documented as not-emitted in `docs/03` §2), unused `NSAppleEventsUsageDescription`, unauthenticated LAN backend (consider a bearer token).
+- Smaller P3s in `EVALUATION.md`: whether to actually emit the `manifest.json` per-file `sha256` (now documented as not-emitted in `docs/03` §2); unauthenticated LAN backend (consider a bearer token).
 
 ## Deferred decisions
 - Cross-device self unification (same person, desktop mic vs phone speakerphone) does not work by voiceprint and is treated as a separate identity; revisit only if a reliable signal emerges (mic-channel-as-self remains the robust path).
