Daneel bc5714b7b7 ax: fix VoiceOver cursor sync and word double-read ...

Bug 1 (VO cursor not following Emacs cursor):
- Remove FocusedUIElementChangedNotification on emacsView (was a no-op:
  VO re-queried the same element)
- For Emacs-initiated char/word moves, keep natural next/previous
  direction instead of forcing discontiguous; SelectedTextChanged with
  direction=next advances VO browse cursor sequentially
- Only force discontiguous for line-boundary crossings and large jumps

Bug 2 (word double-read with punctuation):
- Root cause was FocusedUIElementChanged causing VO re-anchor speech
  on top of the explicit word announcement
- Removing FocusedUIElementChanged eliminates the duplicate speech
- Add emacsInitiated parameter to postFocusedCursorNotification;
  omit AXTextSelectionGranularity for Emacs-initiated moves so VO
  does not auto-speak (only explicit announcements provide speech)
- isWordMove now triggers on emacsInitiated flag (Emacs-initiated
  word moves always get explicit announcement)
