Add cleanup-renamed-repos.sh, which groups Gitea mirrors and gitea-mirror
rows by GitHub repo id, keeps the copy at the current name (renaming a
case-only mismatch in place), deletes the rest and re-imports.
cleanup-archived-repos.sh now deletes every mirror whose GitHub source 404s
when the source belongs to the gh user or an org it administers, keeps
third-party ones, and aborts on a GitHub rate limit.
Deletes the archived-* Gitea copies gitea-mirror keeps when a source in the
given owners disappears, and removes their tracking rows so they are not
re-mirrored. Dry run by default.
The skill reached Gitea on localhost and the mirror database inside the
container, which only worked on a local host. It now uses tea for Gitea
and the gitea-mirror API key for repository status and retries, in bash.
Private upstreams are no longer probed anonymously, which reported them
as deleted.
