feat: Include JACK audio devices in mic dropdown

ae3de55bfe6e535f63c1d1a7c51eaddd7c15c16a · Claude · Jan 25, 2026 23:53

Add JACK devices to the microphone selection list, organized by priority:
1. PipeWire/Pulse virtual devices (most stable routing)
2. ALSA hardware devices
3. JACK devices (prefixed with [JACK] for clarity)

This allows capturing audio from JACK devices like loopback sources
and audio interface outputs for speaker/system audio capture.
