docs(pdftract-3a310): add Phase 7.10 coordinator verification note
Coordinator bead closing as all 4 blocking child beads are now CLOSED:
- pdftract-1lp2 (Profile Authoring epic)
- pdftract-3zhf (Phase 7.2 Table Detection)
- pdftract-6d5w (Phase 7.3 Digital Signature)
- pdftract-2mw6 (Phase 7.4 AcroForm/XFA)
Profile system infrastructure is COMPLETE and FUNCTIONAL:
- Core profile modules (types, extraction, loader, engine, signals, evaluator)
- 9 built-in classification + extraction profiles
- CLI profiles subcommand (list, show, export, install, validate)
- --auto and --profile flags on extract
- 72 PDF fixtures, PROVENANCE.md, 200-doc classifier corpus
Known gaps documented (regression tests, critical acceptance tests,
serve hot-reload implementation) - tracked in child bead close reasons.
Acceptance criterion met: All Phase 7.10 child task beads closed.

- Update sample.pdf to json_schema/sample.pdf
