Subject: feat(mq_editor): f·Power checkbox, deselect on extract, panel refresh
 after auto-spread
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- 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
