feat(gitea-mirror): clean up mirrors left by renamed and deleted repos

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.

## Archived repo cleanup
When a GitHub source disappears, gitea-mirror keeps the Gitea copy, renames it
`archived-<name>`, and keeps tracking it. To drop those copies for the user's
own namespaces:
When a GitHub source disappears, gitea-mirror keeps the Gitea copy, sets its
row to `archived`, and sometimes renames it `archived-<name>`. The rule:
- **Source owned by the user** (the gh user or an org it administers) —
delete the Gitea copy and its gitea-mirror rows. The user deleted the source
on purpose.
- **Third-party source** — keep. It is the only remaining copy of a repository
someone else deleted.
```bash
scripts/cleanup-archived-repos.sh --login <login> --owners <owner1,owner2,...>
scripts/cleanup-archived-repos.sh --login <login> --owners <owner1,owner2,...> --apply
scripts/cleanup-archived-repos.sh --login <login>
scripts/cleanup-archived-repos.sh --login <login> --apply
```
`--owners` is the user's own GitHub users and orgs; ask for them if they are
not known. Only an `archived-*` repo whose gitea-mirror row points at it is
deleted, so a repo the user named that way by hand is skipped. For each one it
deletes the Gitea repo, then removes the tracking row
(`DELETE /api/repositories` with `{"ids": [...]}`) so it is not re-mirrored.
Third-party archived copies stay; they are the only remaining copy of a source
someone else deleted. Show the dry run and get confirmation before `--apply`.
`--owners a,b,c` overrides the owner list, which otherwise comes from
`gh api user` plus `user/memberships/orgs` with role `admin`. Ownership is
judged by the GitHub owner in the mirror's `original_url`, not the Gitea owner.
"Gone" means `gh api repos/<source>` answers HTTP 404. The `gh` token has the
`repo` scope, so a private repository answers normally and only a deleted one
404s; a rename or transfer redirects and is not gone. Row status `archived`
alone is not enough: gitea-mirror also uses it for repositories archived on
GitHub, which still exist. Any other probe failure counts as alive. A hit rate
limit aborts the run, since its probes would silently under-report. Non-mirror
repos, such as the `archived` org, are never touched.
For each target it deletes the Gitea repo, then removes every row pointing at
it (`DELETE /api/repositories` with `{"ids": [...]}`) so it is not re-mirrored.
Show the dry run and get confirmation before `--apply`.
The renamed and archived scripts each probe every mirror through the GitHub
API, about 750 calls per run against a 5,000-an-hour limit; leave time between
runs.
## Renamed repo cleanup
A GitHub rename, transfer or case change leaves the old Gitea copy and the old
gitea-mirror row behind; gitea-mirror tracks rows by name, so the new name gets
a second row and a second copy. To collapse every repository onto its current
name:
```bash
set -a; . <repo-root>/.env; set +a # GITEA_MIRROR_URL, GITEA_MIRROR_API_KEY
scripts/cleanup-renamed-repos.sh --login <login>
scripts/cleanup-renamed-repos.sh --login <login> --apply
```
It needs `gh` logged in. Every Gitea pull mirror and gitea-mirror row is
resolved through `gh api repos/<path>`, which follows GitHub's rename
redirects, and grouped by GitHub repo id. Per group:
- **Keep** the Gitea copy named exactly as on GitHub now; failing that, the one
matching case-insensitively, renamed to the exact case.
- **Delete** every other Gitea copy in the group, third-party repos included.
- **Drop** every row whose name is not exactly current, then re-import from
GitHub (`POST /api/sync`) and queue the renamed repos' new rows
(`POST /api/job/mirror-repo`), which finds the existing copy and marks it
mirrored without re-cloning.
Renaming is safe because gitea-mirror ignores case in both places that
matter: its row identity (lowercased `normalizedFullName`) and its check
that an existing Gitea repo mirrors the same source (lowercased clone URLs).
The old row must go first; while it exists the case-only rename is never
re-imported. Every gitea-mirror `POST` needs a JSON body
(`-H 'Content-Type: application/json' -d '{}'` at minimum); without one Astro
answers 403 "Cross-site POST form submissions are forbidden".
A group with no copy at the current name is left untouched, so a transferred
repo whose new mirror does not exist yet keeps its only copy. Sources GitHub
answers 404 for are listed as skipped, never deleted. Non-mirror repos, such as
the `archived` org, are never touched. A renamed copy keeps its old
`original_url`; GitHub redirects it, so syncing still works. Show the dry run
and get confirmation before `--apply`.
