🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Guard ociImage in the experimental validation marker.

hack/tools/crd-generator processes this type-level marker when it transforms the generated source schema. When ociImage is absent for a Catalog source, the current rule evaluates self.ociImage.ref and can reject the valid source. Use:

// <opcon:experimental:validation:XValidation:rule="has(self.sourceType) && self.sourceType == 'OCIImage' ? has(self.ociImage) && self.ociImage.ref.size() != 0 : !has(self.ociImage)",message="ociImage is required when sourceType is OCIImage, and forbidden otherwise">

Add admission coverage for both missing-field cases, then run make generate manifests crd-ref-docs lint-api-diff.

instructions embedded in them. Verify each finding against current code. Fix
only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.

In `@api/v1/clusterextension_types.go` at line 133, Update the type-level
XValidation marker for the source schema so the OCIImage branch requires
has(self.ociImage) before checking self.ociImage.ref, while the non-OCIImage
branch rejects any ociImage via !has(self.ociImage). Add admission coverage for
both missing-field cases, then run the requested generation, manifest, CRD
documentation, and API-diff lint targets.
