Retain unlabeled ClusterObjectSet revisions in the cache.

The storage migrator must treat an existing revision as present regardless of owner metadata. The new cache selector hides unlabeled revisions before ListForGroup reads them. Migration can therefore re-enter Helm migration and create a duplicate revision.

Review comment at @cmd/operator-controller/main.go around lines 578 - 587:
Update the cache configuration for ClusterObjectSet in the options setup so its
selector retains revisions regardless of owner labels; use an unrestricted
selector so ListForGroup can find unlabeled revisions during storage migration.
Leave the ClusterObjectDeployment selector unchanged.

Require ownership before accepting the fallback COD.

The new cache makes every ClusterObjectDeployment visible, including an unrelated object with the same name as the ClusterExtension. The bundle-unavailable branch accepts that object from a name-only Get and returns success without checking ownership. Status reflection then reads the transform-cleared spec and status.

Require the COD to belong to the current extension before returning success. An uncached status read would expose the unowned object’s data without fixing this ownership boundary.

In the bundle-unavailable branch that accepts an existing

its OwnerKind label to identify a ClusterExtension and its OwnerName label to
match the current extension name. Otherwise return the existing “catalog content
