57577b42c9 Fix Android audio routing - use music stream for speaker output
- Changed audioStreamType from 'voiceCall' to 'music' on Android
  - voiceCall stream defaults to earpiece
  - music stream defaults to speaker
- Added Debug tab to test voice calls with detailed logs
- Added speaker/earpiece toggle button with proper stream switching
- Full Android AudioSession support for LiveKit voice calls

audioSession.ts:
- configureAudioForVoiceCall: uses music/media for speaker output
- setAudioOutput: switches between music (speaker) and voiceCall (earpiece)
- reconfigureAudioForPlayback: ensures speaker output on Android

debug.tsx:
- Added platform info display
- Added speaker toggle with logging
- Improved UI with control rows

059bc29b6b WIP: LiveKit voice call integration with Julia AI agent
NOT TESTED ON REAL DEVICE - simulator only verification

Components:
- LiveKit Cloud agent deployment (julia-agent/julia-ai/)
- React Native LiveKit client (hooks/useLiveKitRoom.ts)
- Voice call screen with audio session management
- WellNuo voice_ask API integration in Python agent

Tech stack:
- LiveKit Cloud for agent hosting
- @livekit/react-native SDK
- Deepgram STT/TTS (via LiveKit Cloud)
- Silero VAD for voice activity detection

Known issues:
- Microphone permissions may need manual testing on real device
- LiveKit audio playback not verified on physical hardware
- Agent greeting audio not confirmed working end-to-end

Next steps:
- Test on physical iOS device
- Verify microphone capture works
- Confirm TTS audio playback
- Test full conversation loop
