The cleanup step ran silently, so a no-op run was indistinguishable
from a broken one. Add a config banner, per-deletion lines, and a
per-package plus grand-total summary with a kept-reason breakdown, and
an explicit message when nothing matches. Add DRY_RUN support.
Deletion rule: delete a version only when it carries a ci-* tag, has no
semver (v*) or latest tag, and is older than MAX_AGE_DAYS. Released
images and untagged multi-arch child layers are never touched.
