Tasks

Add requirement scenarios for resilient transcript workflow writes and workflow diagnostics.
Add a failing behavior test proving transcript text is written when transcript-line workflow rules fail.
Append live transcript lines before workflow transformation and rewrite changed lines afterward.
Add workflow rule completion/error logging.
Update workflow engine documentation.
Run focused tests and openspec validate resilient-transcript-workflow --strict.
Follow up later: investigate anomalous temporary-recording disk-full IOException despite small expected WAV size.
