Drop the #include "MainWindow.h" from WebcamDevice/VideoConsumer/AudioConsumer. - AudioSink interface: AudioConsumer no longer knows about VideoRecorder. It pushes raw PCM to an abstract AudioSink; VideoRecorder implements it and owns the AVI-specific float->int16 conversion (moved out of the capture thread's knowledge). MainWindow wires it via SetAudioSink/ClearAudioSink. src/webcam/ now has no app-layer includes. Behavior is unchanged.

(GetVideoConsumer() stays - still used for raw capture.) - Remove per-buffer heap allocation on the real-time audio thread: VideoRecorder reuses a float->int16 scratch buffer; AudioConsumer reuses a byte-swap scratch buffer (big-endian path) instead of new[]/delete[] per buffer. - Drop the unused audioMessage parameter/member from VideoConsumer. - Replace stray fprintf(stderr) in MainWindow's recording path with the LOG_* macros used elsewhere.
