Review feedback: reported_audio_path was cached at writer-open time
and survived a mid-session writer drop. If an append error cleared
wav_writer (or hound's Drop ran instead of finalize), the Summary
still reported the path — risking StopLiveTranscriptionResponse
pointing at a file whose header did not reflect its data chunk.
Moves the decision to end-of-session. wav_writer.take() is inspected:
- writer present + finalize Ok → report the path,
- writer present + finalize Err → None, emit a Warning,
- writer absent (mid-session drop, or never opened) → None.
StopLiveTranscriptionResponse.audio_path now means "the recording is
known-good" rather than "a recording was attempted". Users can still
recover partial files via filesystem if needed; the warning toasts
already emitted by append_resampled_audio on write failure surface
that path implicitly.
