feat(mq_editor): f·Power checkbox, deselect on extract, panel refresh after auto-spread
- Add 'f·Power' checkbox: weights spectrum by f before peak detection (f·FFT_Power(f))
to accentuate high-frequency peaks; re-runs extraction on toggle
- Deselect partial after Extract Partials run
- Fix right panel not refreshing after Auto Spread All: re-call editor.onPartialSelect
handoff(Claude): mq_editor UX polish
