Why: governance checks validate candidate .gitmodules URLs against the
pinned development-manager scaffold, which now carries the new Gitea
endpoint base after its own migration.
Evidence: host-verified; see Dev PR #706
Impact: pin update only, part of the coordinated endpoint migration.
Refs: Agent-System-Dev PR #706
Why: the Gitea server moved to https://gitea.naitangbaobao.cn with SSH
on port 52222; endpoint references must follow or superproject CI
checkout refuses the old URLs.
Evidence: host-verified API reach and SSH auth (Dev task card
fix/gitea-endpoint-migration)
Impact: configuration only; no runtime behavior change.
