patches: apply all maintainer review fixes (review pass 2)

All 9 patches now apply cleanly with git am on Linux (git 2.43.0).
Root cause of previous failures: hunk offsets were systematically wrong
by 7-40 lines; macOS git fuzzy-matched them, Linux did not.
Patches regenerated via git format-patch after applying all changes.

Fixes applied:
- P0000: unbind_to on no-candidate fall-through path; hunk regenerated
- P0001: block_input + record_unwind_protect_void in ns_ax_buffer_text
- P0003: [trims release] MRC memory leak; block_input already present
- P0004: mojibake comment (--- not UTF-8 em-dash)
- P0006: texinfo dangling semicolons -> periods in GNUstep paragraph
- P0007: em-dash fixes removed (content was already --- from P0004/P0005)
- P0008: childFrameLastBuffer -> BVAR(b,name) for GC safety;
  BUF_OVERLAY_MODIFF removed from ensureTextCache (hl-line-mode O(N)
  rebuild regression); block_input in ns_ax_buffer_text (P0001 scope);
  voiceoverSetPoint and childFrameLastBuffer explicit init in
  initFrameFromEmacs:; cachedOverlayModiffForText ivar removed
