Oliver 813f4254c9 feat: add PlayOnTrigger for music-synced audio playback
- Add PlayOnTrigger method to AudioSystem for scheduling audio playback on music sync events (beat/bar/grid)
- Rename ButtonInvoker to SetStateBind for better clarity
- Update PlaySoundBind to support both direct playback and trigger-based playback with callback flags
- Add CallbackFlags enum (MusicSyncBeat, MusicSyncBar, MusicSyncGrid)
- Update Metronome demo to use new callback flag naming convention
- Add test audio file sfx_notice_test.wav
- Update scene UI to demonstrate PlayOnTrigger functionality
