'Keep voice clips' setting (default off). When on, /api/voice/transcribe saves the audio (0600) to the owner-only ZFS subvol at /var/lib/void/ voice-clips (CT 311 mp0, replicated to Z3) + a voice_clips row (migration 029, transcript+metadata in void-db). New clips list/play/delete API + Settings UI. Storage path is configurable (VOICE_CLIPS_DIR). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
