Correct stale Gitea current-state claims to Forgejo

Forgejo has replaced Gitea as the forge. Updates SCOPE.md Current State,
AGENTS.md and .claude/rules/repo-identity.md, which still described Gitea as
the operational forge.

Deliberately NOT changed, because they are accurate rather than stale:
- migration and coexistence prose in docs/forgejo-on-railiance01.md,
  docs/forge-source-of-truth-decision.md and the capability registry, where
  Gitea is the thing being migrated from
- gitea-charts/gitea 12.5.0, the real Helm chart Forgejo deploys from
- gitea-db, a running CNPG cluster, and the gitea- prefixed doc filenames in
  railiance-forge, which still exist under those names
