Audio

  • Add WASAPI loopback capture for Windows — auto-captures desktop audio (what's playing through speakers) without requiring Stereo Mix
  • WASAPI backend uses windows crate COM APIs: IMMDeviceEnumerator → IAudioClient (loopback) → IAudioCaptureClient
  • Same fallback pattern as Linux: try WASAPI loopback first, fall back to cpal input devices
  • Supports float32, int16, and int24 formats with stereo→mono downmix
  • Device friendly name shown in status bar (e.g. "Speakers (Realtek Audio)")

Bug Fixes

  • Fix webcam "Failed to fulfill requested format" on Windows: cameras that only support raw formats (YUYV/NV12) now work via automatic fallback from MJPEG to any supported format

CI

  • Upload debug build artifacts on PRs for all platforms
