actions/delete-package-versions can't see OCI manifest lists. When the
cpu build pushes a multi-arch image, the registry gets a tagged index
plus one untagged per-platform manifest per arch. The cleanup step with
`delete-only-untagged-versions: true` then deletes the per-platform
children, leaving the index dangling — `docker pull
ghcr.io/mostlygeek/llama-swap:cpu` 404s on the referenced sha.
Swap to dataaxiom/ghcr-cleanup-action, which inspects tagged manifest
lists first and excludes their children from deletion. Single-arch
backends behave the same as before.
