Capture Idea (voice)

Pipeline: audio → transcript → structured idea workspace.

Steps

1. Resolve config (workspace path, user context).
2. Take the audio file path from the user. Verify it exists and looks like an audio file.
3. Transcribe. Prefer the claude-transcription plugin's skills if installed:
   • claude-transcription:transcribe-gemini-cleaned — fastest path, removes filler words
   • claude-transcription:transcribe-gemini-raw — verbatim if the user wants every word preserved
   • Fallback: prompt the user to install claude-transcription or supply an existing transcript.
4. Save the raw transcript to a temp path. Show the user a short preview (first ~200 words) before proceeding.
5. Hand the transcript to capture-idea:
   • Pass the transcript text as the raw input
   • Tag the resulting idea.md frontmatter with source: voice and audio_file: <original-path>
   • Copy the audio file (or symlink) into <workspace_path>/ideas/<idea-slug>/source-audio.<ext> so the recording stays with the workspace
6. Continue through capture-idea's formatted-variant menu so the user can pick which derived versions to generate.
