Add an audio source picker to the GUI so users can capture a specific PipeWire device (sink monitor or microphone) instead of only the system default output. - vendor go2tv.app/screencast and patch the audio stream to accept a target PipeWire node serial (PW_KEY_TARGET_OBJECT); the upstream lib only ever auto-connected to the default - capture: ListAudioSources enumerates PipeWire sinks/sources via pw-dump; OpenPipeWire takes the selected node serial - flinger/config/gui: AudioSource config field, persisted and exposed as an Audio source dropdown (default output + enumerated devices) Also fixes two pre-existing bugs surfaced by stop/start testing: - engine Stop now waits for the video/audio/stats goroutines before destroying the encoder (was a use-after-free SIGSEGV) - Start/Stop now pause/resume the engine instead of tearing down and re-opening the portal session, which the portal cannot reliably do in-process (2nd CreateSession returned Ended/cancelled). Capture session stays open across stop/start.
