feat(pi-notifications): switch to afplay audio instead of desktop notifications

Browse Source 
- Uses afplay to play an audio file (default: Glass.aiff)
- Configurable via PI_NOTIFICATION_AUDIO env var
- Works from sandboxed context — no osascript needed
- test-notify.ts verifies audio playback standalone
- Synced to auto-discovery extension path
