The Dockerfile uses `--mount=type=cache` which requires BuildKit. The static docker tarball only ships the CLI, so the plugin has to be installed separately. Also flip the build step to `docker buildx build --push` so build and push happen in one pass instead of two (avoids the intermediate local-daemon load).
