Daneel a234ded3db Rewrite Zoom a11y patch: NSAccessibility primary, UAZoomChangeFocus supplementary ...

Key changes:
- Add accessibilityFrame on EmacsView returning cursor screen rect
  (the standard mechanism used by Terminal.app, iTerm2, Firefox)
- Guard UAZoomChangeFocus with bundleIdentifier check (bare binaries
  are silently ignored by the window server)
- Extensive English comments explaining both mechanisms
- Deduplicate legacy parameterized attribute via accessibilityBoundsForRange:

Root cause of Stéphane's failure: UAZoomChangeFocus communicates via the
window server which identifies apps by CFBundleIdentifier. Bare binaries
(src/emacs, symlinks) have no bundle ID and are ignored. NSAccessibility
notifications + accessibilityFrame work for ALL launch methods.
