Implement REUSE-WP-0012 federation scale and intent alignment

Add hub sync and report cohorts CLI commands with pytest coverage, document
sibling index publish contract and hub hardening path, align INTENT layout,
raise external evidence on three registry entries, and close gap priorities
19-23 (priority 18 deferred on sibling index blocks).

-      explicit blocks per sibling with owner follow-ups
-- [ ] `hub sync` materializes valid `sources.yaml` from hub state
-- [ ] `report cohorts` (or equivalent) exports planning/implementation filters
-- [ ] `INTENT.md` layout matches delivered repository structure
-- [ ] Hub hardening doc complete; backup/restore steps verified once on Railiance01

+- **T01:** Publish contract in `docs/RegistryFederation.md`; sibling 303 probes in
+  `history/2026-06-16-hub-registration-blocks.md`. Hub remains at 1 repo until
+  siblings publish indexes.
+- **T02:** `reuse_surface/hub_sync.py`, `reuse-surface hub sync`, pytest in
+  `tests/test_hub_sync.py`.
+- **T03:** `reuse_surface/reports.py`, `reuse-surface report cohorts`, pytest in
+  `tests/test_reports.py`.
+- **T04:** `INTENT.md` layout aligned with `SCOPE.md`.
+- **T05:** Hardening section in `docs/deploy/reuse-kubernetes.md`.
+- **T06:** R1→R3 checklist in `registry/README.md`; entries `capability.registry.register`,
+  `capability.registry.validate`, `capability.statehub.progress-log` updated.
