Daneel 54183cc8eb v10 patch: rich SelectedTextChanged for VoiceOver cursor movement ...

Key changes from v9:
- SelectedTextChanged now includes rich userInfo:
  direction (Next/Previous/Discontiguous) and
  granularity (Character/Word/Line) inferred from
  old vs new cursor position comparison
- Track lastAccessibilityCursorPos + lastAccessibilityCursorLine
  ivars for position delta detection
- accessibilityInsertionPointLineNumber: buffer lines (count_lines)
  instead of visual vpos
- accessibilityLineForIndex: buffer lines via count_lines
- accessibilityRangeForLine: buffer lines via find_newline_no_quit
- Skip notification on unchanged position (avoids VO repeating)
- Word granularity heuristic: same line, >1 char delta
