Root cause: Audio from remote participant (Julia AI) was not playing
because room.startAudio() was never called after connecting.
This is REQUIRED by LiveKit WebRTC to enable audio playback.
The fix matches the working implementation in debug.tsx (Robert version).
Changes:
- Add room.startAudio() call after room.connect()
- Add canPlayAudio state tracking
- Add proper error handling for startAudio

- Remove expo-speech (TTS) - not used
- Remove expo-speech-recognition (STT) - not used
- Delete dead code: hooks/useSpeechRecognition.ts
These packages add native audio modules that can conflict with
LiveKit's AudioSession management on iOS.
