patches: fix 3 blockers — duplicate functions, idx typo, doc cap

BLOCKER fixes:
1. Remove duplicate ns_ax_face_is_selected, ns_ax_selected_overlay_text,
   ns_ax_selected_child_frame_text definitions from patch 0002
   (now defined only in 0007/0008 where they belong)
2. Fix idx → point_idx in accessibilityInsertionPointLineNumber (0002)
3. Remove stale 100K cap reference from documentation (0006)

Architecture fix:
- ns_ax_selected_child_frame_text moved from 0007 to 0008
  (where it logically belongs)

Verified: all 8 patches apply cleanly on fresh emacs HEAD.
