Daneel 936c251f11 patches: comprehensive review fixes — B1/W1-4/M1-4 ...

B1: setAccessibilityFocused: on EmacsAccessibilityBuffer now checks
    ![NSThread isMainThread] and dispatches to main via dispatch_async.
    Prevents data race + AppKit thread violation from AX server thread.

W1: accessibilityInsertionPointLineNumber and accessibilityLineForIndex:
    now use lineRangeForRange iteration — O(lines) instead of O(chars).

W2: ns_ax_scan_interactive_spans skips non-interactive regions using
    Fnext_single_property_change for each scannable property and
    Fnext_single_char_property_change for keymap overlays.

W3: ns_ax_event_is_line_nav_key inspects Vthis_command against known
    navigation command symbols (next-line, previous-line, evil variants,
    dired variants) instead of raw key codes. Tab/backtab fallback
    retained via last_command_event.

W4: DEFSYM symbols renamed with ns_ax_ prefix (Qns_ax_button, etc.)
    to avoid linker collisions with other Emacs source files.
    Lisp symbol strings unchanged.

M3: Removed dead enum values (CheckBox, TextField, PopUpButton) and
    corresponding dead switch cases.

M4: Improved accessibilityStyleRangeForIndex: comment documenting the
    line-granularity simplification.

README: Updated stats, KNOWN LIMITATIONS, DEFSYM docs, test numbering.
