feat(mq_editor): implement MQ extraction improvements

- Implement Predictive Kinematic Tracking to improve partial tracking during fast glissandos and vibrato.
- Add Peak Prominence Pruning to filter out insignificant local maxima.
- Replace heuristic Bezier fitting with a Least-Squares solver for more accurate trajectories.
- Update UI to include a Prominence parameter input.
- Archive MQ_EXTRACTION_IMPROVEMENTS.md design document.

handoff(Gemini): implemented MQ extraction improvements (kinematic tracking, prominence pruning, least-squares bezier)
