Extract duplicated code (Whisper loading, audio recording, transcription,
VAD processing) into reusable sttlib/ package. Rewrite all 3 scripts as
thin wrappers. Add 24 unit tests with mocked hardware. Fix GPU fallback
bug in assistant.py and args.system assignment bug.
New tool that uses webrtcvad for voice activity detection, faster-whisper
for transcription, and xdotool to type into any focused window. Supports
session-based listening, configurable silence threshold, and a "full stop"
magic word to auto-submit.
