Both desktop mics were hard-mono: the core defaults capture_channels=1 and neither client ever called vc_set_capture_channels (only iOS did). Add a persisted "Stereo microphone" toggle to each client's Audio settings, applied when the mic stream starts and live via vc_set_capture_channels + vc_audio_restart. Expose both ABI calls in the Windows interop; the macOS wrapper already had them. Core fix: encode_and_send_frame now folds a stereo mic frame to mono on a mono channel - previously the channels==2 branch encoded interleaved L/R directly even on a mono channel, feeding a mono opus_encode 2x its samples (wrong pitch/garbage). Real stereo still only reaches the wire on a stereo channel; on a mono channel the mic is cleanly downmixed. Test: test_stereo_mic_mono_channel. ctest --preset dev green (28/28). Docs: voice.md.
