patches: address all maintainer review issues

- Issue 1: Add explicit ApplicationServices import for UAZoomEnabled/
  UAZoomChangeFocus (was implicit via Carbon.h, now explicit)
- Issue 2: Rename FOR_EACH_FRAME variable 'frames' -> 'frame' (plural
  was misleading; matches Emacs convention)
- Issue 3: Move unblock_input before ObjC calls in
  postCompletionAnnouncementForBuffer: to avoid holding block_input
  during @synchronized operations
- Issue 4: Fix DEFVAR_BOOL doc and Texinfo: initial value is nil,
  not t; auto-detection sets it at startup
- Issue 5: Replace magic 10000 with NS_AX_MAX_COMPLETION_BUFFER_CHARS
  constant with explanatory comment
- Issue 6: Add comment to lineStartOffsets loop explaining it is gated
  on BUF_CHARS_MODIFF and never runs on the hot path
- Issue 8: Rewrite all 9 commit messages to GNU ChangeLog format with
  '* file (symbol): description' entries
- Issue 9: Break 81-char @interface line in nsterm.h
- Issue 10: Add WINDOWP/BUFFERP guards before dereferencing
  cf->selected_window and cw->contents in ns_zoom_find_child_frame_candidate
- Issue 11: Fix @pxref -> @xref at sentence start in macos.texi
