Refactor the audio pipeline to support multi-client streaming with new OggFlacStreamHandle and StreamingOggFlacSink. - Replace DirectOggFlacSink with StreamingOggFlacSink in pipeline - Update documentation and comments to reflect multi-client support - Add detailed warning logs for buffer underruns and client disconnections - Remove TimerBufferNode from pipeline as it's no longer needed - Update connect() calls to subscribe() for new streaming behavior This change enables multiple clients to subscribe to the same audio stream, with each subscription getting a live feed from the current point in time.
