charposForAccessibilityIndex: walked composed character sequences from the start of a visible run to the target AX index. For a run covering an entire ASCII buffer, this is O(cursor_position): moving to line 10,000 requires ~500,000 iterations per call. The method is called on every SelectedTextChanged notification response (accessibilityBoundsForRange: from the AX server for cursor tracking), making cursor movement O(position) in large files. Fix: when ax_length == length for a run (all characters are single AX index units — true for all ASCII/Latin text), the charpos offset is simply ax_idx - run.ax_start. O(1) instead of O(position). Multi-byte runs (emoji, CJK, non-BMP) fall back to the sequence walk, bounded by run length (visible window size), not total buffer size.
