spec-riffrec-feedback-analysis

Analyze explicit Riffrec product-feedback captures, including riffrec-*.zip, the Riffrec session.json + events.json + recording.webm + voice.webm bundle, or media/notes the user identifies as a Riffrec feedback capture. Also use for Riffrec setup and capture guidance. Do not trigger for generic podcasts, meetings, audio/video transcription, or unrelated capture/share requests.
