Fix Web Speech API desktop voice recognition

- Set continuous=true to keep listening through pauses
- Only process final results, ignore interim transcripts
- Add usesFallback check to route Web Speech API transcripts through classification
- Desktop now captures complete phrases before classification
- Add detailed logging for debugging recognition flow
