feat(WP-0009): IHF GAAF Compliance Foundation — type registries, extension manifests, architectural contracts

Implements IHUB-WP-0009: closes four GAAF-2026 gaps before domain hub work begins.
- TypeRegistry helper + controllers/views (hub_kind, hub_capability_manifest)
- HubCapabilityManifest entity with validation and registry linkage
- ARCHITECTURE-LAYERS.md + CI-enforced boundary contracts
- Alembic migration 1743724800, fitness tests (Test/Architecture/)
- GAAF spec, Operational Architecture spec, domain hub extension guide
- Updates to CLAUDE.md, SCOPE.md, Schema.sql, Routes, FrontController, Types

state_hub_sync: pending (tunnel was STALE at completion time; run fix-consistency)
