Subject: [PATCH] ns: implement VoiceOver accessibility (AXBoundsForRange, line
nav, completions, interactive spans)
* src/nsterm.h (EmacsAccessibilityElement): New base class.
(EmacsAccessibilityBuffer): AXTextArea/AXTextField per window.
(EmacsAccessibilityModeLine): AXStaticText for mode line.
(EmacsAccessibilityInteractiveSpan): Focusable spans.
(ns_ax_visible_run): Visible buffer range to AX index mapping.
* src/nsterm.h (EmacsAccessibilityElement, EmacsAccessibilityBuffer,
EmacsAccessibilityModeLine, EmacsAccessibilityInteractiveSpan,
ns_ax_visible_run): New types for virtual accessibility tree.
* src/nsterm.m (ns_ax_buffer_text): Build AX string with
record_unwind_current_buffer for exception safety.
(ns_ax_utf16_length_for_buffer_range): UTF-16 length with
record_unwind_current_buffer.
(ns_ax_completion_text_for_span): Completion text extraction with
record_unwind_current_buffer.
(ns_ax_find_completion_overlay_range): Fast 3-probe + Foverlays_in
bulk fallback.
(ns_ax_event_is_line_nav_key): Detect C-n/C-p/Tab/backtab.
(ns_ax_scan_interactive_spans): Forward scan for interactive props.
(postAccessibilityUpdates): Re-entrance-guarded dispatcher.
(rebuildAccessibilityTree): Build virtual AX element tree.
(postAccessibilityNotificationsForFrame:): Hybrid notification
strategy with record_unwind_current_buffer.
(invalidateTextCache, ensureTextCache): @synchronized for
thread safety of visibleRuns/cachedText.
(accessibilityIndexForCharpos:, charposForAccessibilityIndex:):
Thread-safe index mapping with @synchronized.
(ns_draw_phys_cursor): UAZoomChangeFocus with version guard.
* src/nsterm.m: Full VoiceOver/Zoom support with thread-safe caching,
record_unwind_current_buffer for all buffer switches, @synchronized
for cross-thread data access, NSTRACE debugging, Foverlays_in bulk
queries, and MAC_OS_X_VERSION guard for UAZoom APIs.
* etc/NEWS: Announce VoiceOver accessibility on macOS.
