Adds "only selected apps" and "all apps except selected" screen-audio modes to the Windows client, alongside the existing entire-desktop path. Per-app capture uses WASAPI process loopback (AUDCLNT_ACTIVATIONTYPE_ PROCESS_LOOPBACK) via ProcessLoopbackCapture, mixed by ProcessAudioMixer and fed to the core through vc_stream_feed_pcm (external_feed=1 so the core skips its own loopback device). Init must pass AUDCLNT_STREAMFLAGS_LOOPBACK | EVENTCALLBACK | AUTOCONVERTPCM; the LOOPBACK flag is what makes the virtual endpoint deliver rendered audio (without it every buffer is flagged SILENT) and AUTOCONVERTPCM resamples the app's native format to 48k s16.
