Publish images to GHCR and releases to the GitHub mirror

- retag+push the same :latest/:X.Y/:X.Y.Z tags to ghcr.io/djeex/socat-proxy
- create a matching GitHub Release on the Djeex/socat-proxy mirror, same changelog
  body prefixed with a notice pointing back to the git.djeex.fr source repo
- targets the exact commit SHA (not the branch) with retries, since the
  Gitea->GitHub push mirror can lag behind this job
- requires a new GH_TOKEN secret (repo + write:packages) — not created yet
- first GHCR push per repo will be private by default; GitHub has no API to
  default it public for a personal account, needs a one-time manual toggle
