docs(pdftract-dejqs): update verification note with 2026-05-22 test results

Re-verified per-page Resource dictionary inheritance implementation:
- All 33 tests pass (resources + pages)
- Arc sharing optimization confirmed (Arc::ptr_eq test)
- INV-8 maintained (proptests pass)

Acceptance criteria:
- ✅ 3-level resource inheritance
- ✅ Per-key override semantics
- ✅ Arc sharing when no merge needed
- ✅ ColorSpace inline arrays preserved
- ✅ Empty root /Resources propagation
