feat(WP-0011): IHF Phase 10 — Hub Registry and Widget Marketplace

Delivers the hub registry discovery UI, widget pattern library,
governance template library, and marketplace dashboard.

Key changes:
- Schema: widget_patterns (widget_type FK to registry), widget_pattern_versions,
  pattern_adoptions, governance_templates (categories JSONB, validated at
  controller), governance_template_clones — all GAAF-compliant, no bare TEXT
  type discriminators
- Migration: 1743897600-ihf-phase10-hub-registry.sql
- HubRegistry controller + views: browsable view over hub_capability_manifests,
  hub_health_snapshots, hubs with per-hub GAAF compliance indicator
- WidgetPatterns controller + views: publish, version, adopt; adoption
  triggers manifest amendment draft when new types are introduced
- GovernanceTemplates controller + views: CRUD, clone with category
  validation against annotation_category_registry
- MarketplaceDashboard controller + view: full-text search, widget-type
  filter, sort, trending panel, autoRefresh
- API v2: /api/v2/hub-registry, /api/v2/widget-patterns (+ adopt endpoint)
- OpenAPI spec updated with Phase 10 paths
- GAAF scorecard: Customization 2.5 → 3.2; overall 3.41 → 3.56 (Strong)
- CLAUDE.md: Phase 10 complete; active workplan → Phase 11
