Forgejo Actions synthesizes a GITHUB_TOKEN for the Forgejo API, not
github.com. Using it to docker-login to ghcr.io always fails (401).
Forgejo side is the new primary — push to the local registry only.
ghcr.io mirroring, if ever wanted, will go through a separate job with
an explicit GitHub PAT in GHCR_TOKEN secret.
Forgejo Actions runner on the stage server picks up these jobs. Runs on
the same labels `[self-hosted, linux]` — same self-hosted box as the
Docker registry and the stage itself.
deploy-stage is simplified: no SSH round-trip (runner and stage are the
same host), just `cp` + `docker compose pull/up`.
POS job kept as-is; it's gated on tag/dispatch and a Windows runner, so
on Forgejo it'll simply not match any runner and stay queued — that's
fine, POS ships from tags only.
