v0.2.0: System tray, IPC status, VAD, hotkey grab, and polish

- Add system tray icon with Exit menu (tray-icon/muda)
- Add IPC daemon status via named pipe (Windows) / Unix socket (Linux)
- Add `mouth status` command to query running daemon
- Add daemon lock to prevent multiple instances
- Hide Windows console window when running as daemon
- Wire up Silero VAD model download and speech filtering
- Switch hotkey listener from rdev::listen to rdev::grab to consume hotkeys
- Add hotkey capture mode in interactive config (press keys instead of typing)
- Add all missing key names (brackets, punctuation, numpad, etc.)
- Fix ONNX tensor type mismatches (encoder wants i64, decoder wants i32)
- Add 300ms lead-in silence to compensate for mic startup latency
- Add 300ms trailing recording after stop for speech not to be clipped
- Add 50ms silence before audio feedback blips for device warmup
- Reduce overlay size (150x18, was 200x36)
- Add PolyForm Noncommercial 1.0.0 license
- Flesh out user-focused README
- Update release script with Gitea/GitHub forge support
