[wip]OPRUN-4764: CSV: Extend RelatedImage with labels - #524
Add the optional labels field to the ClusterServiceVersion type RelatedImage, so operator authors can classify related images by product feature in the bundle's CSV.
The field is optional and additive: CSVs that do not use it are unchanged, and the meaning of the existing name and image fields is unchanged. Keys and values follow the Kubernetes label syntax and constraints; the syntax is validated by opm validate, not here.
Jira: OPRUN-4764
Summary by CodeRabbit
New Features
Related images can include optional Kubernetes-style labels for organization and selection.
Documentation explains how label selectors affect image mirroring and notes that generated bundles may omit labels.
Validation
Related-image labels are checked for valid Kubernetes label keys and values, with clear errors for invalid metadata.

Walkthrough
RelatedImage and its CRD schema now support optional string labels. Deep-copy logic preserves map independence, JSON tests cover label states, and bundle validation checks Kubernetes label syntax.
RelatedImage now has an optional Labels map. The CRD schema defines labels as an object with string values and documents selection behavior. The embedded CRD asset was updated.
Copy and serialization behavior pkg/operators/v1alpha1/zz_generated.deepcopy.go, pkg/operators/v1alpha1/types_test.go
Deep-copy logic creates independent label maps. Tests cover JSON round trips for missing, empty, and populated labels.
Bundle validation checks label keys and values with Kubernetes rules, sorts keys for stable error ordering, and reports field paths. Tests cover valid and invalid labels.
operator-framework/api#532: Updates the controller-gen version annotation in the same CRD file and changes the generator pin that affects CRD output.
operator-framework/api#530: Regenerates the same CRD and embedded definitions, including schema changes in those generated artifacts.

Explanation
The title "[wip]OPRUN-4764: CSV: Extend RelatedImage with labels" names the main change: an optional labels field added to the ClusterServiceVersion RelatedImage type. The changeset matches this. The CRD schema, Go struct, deepcopy code, validation logic, and tests all carry the new labels field. The title has a "[wip]" marker, which signals the PR is not final. That marker does not make the title unrelated to the change.

Operator authors can label the related images of a bundle, typically to say
which product feature each image belongs to. Add a `selectors` field to each
operator package of the ImageSetConfiguration so that disconnected users can
leave the images of the features they do not use behind.
A related image is mirrored when it carries no label at all, or when at least
one selector of its package matches its labels. The requirements within a
selector are ANDed and the selectors of a package are ORed, following the
Kubernetes label selector semantics. A package with no selector mirrors only
the images without labels, so catalogs that carry no label are mirrored exactly
as before.
The selection happens in handleRelatedImages, where the labels of the image and
the package of its bundle are both at hand, which also keeps the images left out
from reaching the copy image schema map. Every image left out is logged for
supportability. All three workflows go through collectOperator, so m2m, m2d and
d2m behave alike. Malformed selectors are rejected when the configuration is
loaded rather than halfway through a mirror.
The labels are read from declcfg.RelatedImage.Labels, which is not released yet,
hence the replace directives pointing at the branches of
operator-framework/operator-registry#2089 and operator-framework/api#524. The
former requires go 1.26.5, which bumps the go directive of this module.

Validate RelatedImage.Labels in the bundle validator.validateRelatedImages runs through the exported BundleValidator and DefaultBundleValidators path, but it checks only RelatedImage.Image. A related image with a valid image reference and malformed label keys or values therefore produces no validation error, despite RelatedImage.Labels documenting the Kubernetes label syntax contract. Validate both label keys and values in this path.

Clarify in the GoDoc of RelatedImage.Labels that labeling a related
image makes it optional for mirroring: `oc-mirror` mirrors a labeled
image only if the entry for its package in the ImageSetConfiguration
carries a selector matching the labels, and skips it otherwise.
Unlabeled related images are always mirrored.
Regenerate the CRD, gzipped definitions, and OpenAPI artifacts that
embed the field description.

Populate structured validation errors with the related-image label path in Field and the invalid key or value in BadValue. Add regression coverage for both errors.
