Expected Behavior:

• Files in general should not be copied to or served from a registry, as they are not valid OCI resources.
• Files with special characters in their names should be explicitly excluded from hauler store copy and hauler store serve registry operations. If handling such files is unsupported, validation should prevent them from being added to the store in the first place.

Actual Behavior:

• Non-OCI resources are copied into the registry or served, and Files with special characters in their names may crash the command
