actions/checkout is a JS action and needs Node to run inside the job
container. The docker-build runner's job image (docker:27-cli, Alpine,
just the Docker CLI) has no Node, so the step failed immediately with
"exec: node: executable file not found in $PATH" - confirmed via the
run's actual log (build-images failed after 16s on every push since the
image-in-CI switch, including the just-merged duplicate-mount and
if:always() fixes). Alpine has apk/git, so clone directly instead.
