Ada de59b6327c Add nix-snapshotter support to the embedded containerd 
Add support for the "nix" snapshotter, which enables running container
images built with nix2container. Nix images reference store paths
directly, avoiding layer tarballs and enabling deduplication through
the nix store.

Changes:
- Register nix-snapshotter as a builtin containerd plugin
- Add NixSupported() validation (checks nix-store is in PATH)
- Configure nix-snapshotter image service proxy in V2/V3 templates
  with containerd_address for CRI image operations
- Add Transfer service unpack_config with differ=walking for
  multi-arch support
- Use containerd state dir for socket path (rootless compatible)
- Disable NRI in rootless mode to prevent bind failures

Usage: k3s server --snapshotter nix
