de1c1e51aa Add hybrid streaming transcription for improved accuracy 
- Implement real-time streaming preview using Parakeet EOU (160ms chunks)
- Add batch transcription on completion for accurate final result
- Prefer Whisper large-v3-turbo (2.7% WER) over Parakeet (6.05% WER) when available
- Remove audio preprocessing that hurts ASR accuracy (gain control, noise reduction)
- Add streaming audio callback support in Recorder and CoreAudioRecorder
- Raw audio passthrough - SDK handles resampling internally
