pstruebi c681e4ce39 feat: refactor audio input to use dedicated reader thread instead of per-frame executor ...

- Replaced per-frame `run_in_executor` calls with single background reader thread in `ThreadedAudioInput`
- Reader thread continuously calls `_read()` and enqueues data via `call_soon_threadsafe` to asyncio.Queue
- Reduces per-frame scheduling overhead and context-switch jitter while preserving async API
- Added thread lifecycle management: lazy start on first `frames()` call, graceful stop in `aclose()`
- Update
