NOT exercised: `npm run dev` / Electron GUI launch (Electron binary download failed, no X DISPLAY in VM), `npm test`, lint/i18n checks, and actual per-app capture of a playing stream (no audio app running). isSupported() depends on a PulseAudio/PipeWire server being reachable; the probe requires it to still be running when the checker runs.",
