patches: reduce completion tracking rate-limit from 500ms to 50ms

Browse Source 
500ms (2 Hz) was too aggressive — Zoom focus stopped updating during
keyboard navigation in Vertico/Corfu lists.  50ms (20 Hz) tracks
fast arrow-key navigation while still avoiding per-frame overhead.
UAZoomEnabled() is already cached so the main cost is the overlay
scan, which is cheap.
