vf-feedback

Log one line of feedback about how Voice Forge behaved.

1. The words after the command are the feedback. If there are none, ask: "What went wrong, and what did you expect?"
2. Run, from this skill's folder: python3 ../voice-forge/scripts/vf.py feedback "<the user's words>" --tool <this agent's name> --mode <the Voice Forge mode in use, if any> It adds a dated line to feedback.md in the voice home and saves it to the private repo.
3. Keep the user's words. Do not rewrite or soften them.
4. Without a shell, give the user the line to paste at the end of feedback.md.
