use window manager to determine device rotation in android

Implements HLS-compatible fragmented MP4 recording on Android using
AndroidX Media3 FragmentedMp4Muxer, matching the iOS implementation.

Changes:
- Add FragmentedRecordingManager for fMP4 segment output
- Add ChunkedRecorderInterface to abstract recorder implementations
- Add onInitSegmentReady callback for init segment (init.mp4)
- Update onVideoChunkReady to include segment duration
- RecordingSession now uses FragmentedRecordingManager by default
