xullul a453112151 M7: read each grouped form once and check PUA alternate meanings ...

Change:
- Leave a form found to be artwork, or refused for a reason in the form
  itself, out of later preparation passes, so a page with many logos or
  unsupported groups no longer reaches the 64-placement limit and prepares
  nothing. ungroup_ops now marks each refusal as intrinsic or contextual;
  contextual ones (translucency, the resources it would merge into, pattern
  placement, the decode budget) are re-evaluated where the form appears, so
  a form refused in one place is still prepared where a parent draws it.
- Refuse a page-level Do with an operand too many for that placement only:
  the form found by its first operand may not be the one drawn. Check a
  form's own operand counts before the nested walk, as an intrinsic refusal.
- Use the Windows PUA alternates only when every kept alternate whose code
  the PDF's map names a Thai character names that alternate's base
  character, so alternates in another order that the map reveals are refused.

Chores:
- Say that the font program confirms each recovered glyph's advance class,
  not its identity, and document the alternate check.

Validation: with and without craft-fonts, fonts 105 (+3 build-input), edit
468, engine 482 (+28 integration) and automation 50 + 352 passed; editor flows
248 passed. Formatting, strict Clippy, layers, assets and parity passed; the
wasm check was not run locally. Each new regression failed with its fix
reverted. Real-PDF edits on Royal Gazette 26288 kept their source fonts.
