Unpacks transcription info instead of discarding it. Adds language and
language_probability fields to transcript events, and includes them in
verbose log output.

--language: force language detection (e.g. en, sv) or leave unset for auto
--task: transcribe (default) or translate to English
Previously language was hardcoded to 'en' which caused multilingual models
to hallucinate translations instead of transcribing the source language.

Checks cache first with local_files_only=True; if the model isn't present
logs "downloading model ..." to stderr before WhisperModel triggers the
actual download.

Errors always go to stderr. Info logs (startup, VAD events, transcripts)
only appear with --verbose / -v, keeping stderr clean when running as a
system service.

Every connection receives the full event stream (vad_start, vad_end,
transcript, error) from the moment it connects — no subscription
handshake required. The asyncio WebSocket server runs in a daemon thread
alongside the VAD loop and transcription thread. Events still go to
stdout unchanged.
Port is configurable via STT_PORT env var (default: 11501).
Add websockets to both setup scripts.

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.
