docs(policy): add Repository Definition of Integrated (DoI)

Three-tier checklist defining what 'fully integrated with the state-hub'
means for a repository:
- Core (Registered): registered, domain assigned, path resolves, remote URL
- Standard (Integrated): SCOPE.md, CLAUDE.md, workplan convention, SBOM, TPSC
- Full (Fully Integrated): repo goal, capabilities declared, agents template,
  clean consistency check, host paths registered

Exposed via /policy/repo-doi (editable in dashboard) and linked under Policies.
