- Remove dead files: message-capture/broadcaster.ts, voice-recording/index.ts
- Fix WebSocket voice_command payload to forward from frontend
- Implement moderation:action handler in commandHandler
- Fix useMascotChat to use canonical request() wrapper
- Fix useAudioPlayback userId hash collision (use string not parseInt)
- Add catch blocks to useMediaControl.skip/stop
- Add typed broadcast functions (messageAnalyzed, voicePcmData, voiceActiveUser)
- Apply Biome formatting and lint fixes
