 New classes:
 - EmacsAccessibilityElement: base class with coordinate conversion
-  (Emacs pixel coords → NSView → screen coordinates)
+- EmacsAccessibilityBuffer: AXTextArea virtual element per Emacs window
-- EmacsAccessibilityBuffer: AXTextArea virtual element, one per visible
-  Emacs window, implementing full text navigation protocol
 
-EmacsView changes:
+EmacsView becomes an AXGroup containing EmacsAccessibilityBuffer children.
-- Role: AXGroup (container for buffer elements)
+Notification hooks fire on cursor movement, text edits, and window changes.
-- Dynamic children built by walking Emacs window tree
-  (FRAME_ROOT_WINDOW traversal, WINDOW_LEAF_P filtering)
-- postAccessibilityUpdates called from ns_update_end hook
-- Notifications: AXValueChanged (rich typing echo on edits),
-  AXSelectedTextChanged, AXFocusedUIElementChanged
-
-Text extraction via glyph row iteration (CHAR_GLYPH glyphs),
-exposing exactly what is rendered on screen, capped at 32KB.
-Point-to-index mapping uses glyph charpos for accuracy.
-Line navigation uses glyph_row vpos (visual screen lines).
-
-UAZoomChangeFocus() retained for macOS Zoom viewport tracking.
-
-Architecture modeled after TextMate's OakTextView accessibility
-(~300 lines manual accessibility on custom NSView) and Xcode's
-AXGroup → AXTextArea virtual element pattern.

-Not implemented (future work):
-- Minibuffer/echo area element
-- Modeline element
-- Attributed text with font/color info
-- Custom VoiceOver rotors
-- Editing via accessibility API (setAccessibilityValue:)
