patches: auto-detect Zoom/VoiceOver; single variable gates both

Changes:
- EmacsApp gets ns_update_accessibility_state and
  ns_accessibility_did_change: methods (patch 0005)
- At startup: UAZoomEnabled() + AXIsProcessTrustedWithOptions()
  determine initial ns_accessibility_enabled state
- com.apple.accessibility.api distributed notification updates it
  whenever any AT connects or disconnects
- All Zoom call sites (UAZoomChangeFocus) now gated by
  ns_accessibility_enabled in addition to ns_zoom_enabled_p()
- ns-accessibility-enabled docstring updated to describe auto-detect

Result: zero config needed; zero overhead when no AT is active;
single variable overrides auto-detection when needed.
