Replaced the original pseudo-version pin, which moved out of the scanner's vulnerable range without containing the docker cp fix, with an upgrade to go-containerregistry 0.21.7. That drops github.com/docker/docker from the graph in favour of moby/moby/client; go list -deps confirms none of the affected code is linked. CI green.
