patches: add Zoom completion tracking (overlay + child frame)

Zoom patch 0000 now tracks completion candidates:
- Overlay: Vertico, Icomplete, Ivy (face heuristic on before-string)
- Child frame: Corfu, Company-box (scan buffer text for selected face)
Also fixes duplicate lastCursorRect ivar when applied with VoiceOver.
