Add .gitea/workflows/release.yml: on v* tag push (or manual
dispatch) build the Docker image and push
git.linuxhg.com/games-database/games-frontend:<tag> plus
:latest, then create/update the Gitea Release from the
annotated tag message. No build-args needed since the build
is env-free. Main-branch pushes do nothing.
Add cliff.toml (conventional-commit release notes), Makefile
release target, and ./release wrapper (accepts 1.0 or v1.0).
Same flow as the other repos; needs a REGISTRY_TOKEN repo
Actions secret (PAT with write:package and write:repository).
