Two follow-ups from hands-free testing:
- Audio cues had no off-switch: empty sound fields fall back to the freedesktop
system chime, so wakeword/recording always made noise. Add a [sounds] enabled
master flag (default true) exposed as "Play audio cues" in Settings → Input.
When off, _play_cue/_play_sound are no-ops — fully silent operation.
- The VAD level meter (sounddevice/PortAudio) leaked harmless thread-teardown
errors ("pthread_join ... failed", "PaUnixThread_Terminate ... failed") to the
terminal on every clip end. PortAudio writes these straight to fd 2, so wrap
the stream open/close in a fd-level stderr suppressor (_quiet_c_stderr).
Tests: cue gating respects the master switch (16 passed).

New GTK settings with a dropdown+editor pattern across four tabs:
- Presets: select/add/delete prompt presets; edit name, keywords, hotkey, mode,
per-preset model/temperature, and a clearly-bordered prompt textfield.
- Engines: STT and LLM engine managers with green/red online-offline status
dots, add/edit/delete, active selector, and an STT record-and-benchmark Test.
- Input: input scheme + keys + quality-gate settings.
- General: microphone picker with a live sounddevice level meter, output,
language, notifications, launch-on-login toggle, and local-Whisper settings.
Adds audio.py (mic enumeration via pactl + LevelMeter) and autostart.py
(~/.config/autostart entry). Recorder + daemon honour the selected mic.
Requirements gain sounddevice + tomli-w.
