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
