Workflows move to .gitea/workflows, which Gitea prefers over
.github/workflows when both exist.
GitHub Actions can only resolve `uses:` against github.com, so the
README now spells out both forms: the full Gitea URL, and the
checkout-then-`uses: ./` fallback for a GitHub workflow that has no
mirror of this repository.
A dependency-free node20 action that triggers application.deploy or
compose.deploy, then follows the deployment to a terminal status so a
failed build fails the CI run. Snapshots the deployment list before
triggering, so a concurrent deployment is never mistaken for this one.
Optionally points the application at a freshly built image first, which
is what lets a workflow lint, test, push and deploy the same artifact.
