Add stt-server.py: self-contained recording + VAD + transcription process

Browse Source 
Replaces the old stdin/stdout transcription-only server. Now handles the
full pipeline in Python:
- Launches parec or arecord for mic capture
- Runs Silero VAD (via silero-vad, already a faster-whisper dep — no sherpa-onnx needed)
- Pre-roll ring buffer (0.2s) prepended to each segment for context
- Transcribes with faster-whisper in a separate thread (GPU not blocking VAD)
- Emits JSON line events to stdout: ready, vad_start, vad_end, transcript, error

Event protocol is designed to map directly to WebSocket subscriptions later.
