perf(mq_editor): move playhead to overlay canvas, avoid full render on tick
setPlayheadTime() now updates only the playhead overlay and spectrum panel
instead of triggering a full renderSpectrogram() every rAF tick.
handoff(Gemini): playhead is now an overlay canvas (like cursorCanvas),
no more O(n_frames) redraw during playback.
