chore: bump version to 2.0.10 [skip ci]

start_transcription() blocks up to 15s waiting for the Deepgram
WebSocket to connect. Running it synchronously in the async endpoint
blocked the entire uvicorn event loop, preventing:
- pollStatus from completing (frozen HTTP request)
- WebSocket broadcasts from being sent
- Any other API requests from being handled

Fix: run start/stop/reload in thread pool via run_in_executor so
the event loop stays responsive during long-running operations.

+
+```bash
+xattr -cr "/Applications/Local Transcription.app"
+```
+
+Then open the app normally. You only need to do this once after downloading.
