📄 Description

Vendor a minimal containerd proxy snapshotter that bind-mounts an existing host rootfs directory as a container's root filesystem — no image pull, no layer unpacking, zero copy. Ships a 'register' command that maps a placeholder image's chain ID to the directory, with optional -image-metadata to preserve the original image's ENV/ENTRYPOINT/CMD.
