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.
