Separate enum validation and the type addition between standard and experimental, such that only experimental adds the support for the new enum/type since this appears to be behind the experimental only BoxcutterRuntime feature gate?

Use a value field for optional OCIImage.

Declare it as OCIImageSource with json:"ociImage,omitzero", then run make generate manifests crd-ref-docs and make lint-api-diff.

minimal, and validate.

In `@api/v1/clusterextension_types.go` at line 161, Update the OCIImage field to
use the OCIImageSource value type and the json tag with omitzero instead of a
pointer and omitempty. Regenerate artifacts with the requested make targets and
run the API diff lint.

Handle registry ports before validating the tag or digest.

self.find(":.*$") starts at the registry port. A valid reference such as registry.example:5000/ns/operator:latest can fail the tag rules because the extracted value contains /. A digest reference with a registry port can fail the digest length and hexadecimal checks for the same reason. Parse after the repository path or use a complete reference validator. Add admission cases for both forms.
