Created the basic structure for OGG-FLAC streaming sink with:
- OggFlacStreamHandle for HTTP client subscriptions
- OggFlacClientStream implementing AsyncRead
- StreamingOggFlacSinkLogic with metadata tracking
- TrackBoundary detection for OGG chaining (TODO)
Structure follows StreamingFlacSink pattern but designed for:
1. OGG container wrapping around FLAC frames
2. OGG chaining on TrackBoundary markers
3. Vorbis Comments metadata updates per track
LIMITATION: Cannot compile/test due to missing system dependencies
(alsa-sys, libsoxr-sys). The code structure is complete but encoding
logic needs to be implemented and tested on a machine with proper deps.
Next steps:
- Implement chunk_to_pcm_bytes conversion
- Implement OGG page wrapper task
- Implement OGG chaining logic
- Test on system with alsa-dev installed
