This PR makes ClusterExtension.spec.namespace optional by introducing “managed namespace” behavior resolved from bundle CSV annotations (including PSA label support), and updates reconciliation + tests/docs accordingly.
Changes:
- Add managed-namespace resolution from bundle metadata with a fallback chain and persist the resolved namespace in status.
- Inject a managed Namespace object (with collision protection) and support applying PSA labels via
suggested-namespace-template. - Expand E2E/unit tests and update CRD schema/docs to reflect optional namespace + immutability rules.

I think we may want to refactor to deprecate spec.namespace, register a new field in the registry+v1 config schema for namespace. And then implement the logic on the bundle converter, which already reads and applies the config.
Would that work?

Nit: Remove In the experimental configuration. When we promote this to standard, we can ideally use the experimental text verbatim, and not have to remember to update the text as well.

Sorry didn't notice this on my first comment about the CRD changes: Let's leave the standard configuration CRD completely unchanged. When we re-gen the CRDs, I'd expect helm/olmv1/base/operator-controller/crd/standard/olm.operatorframework.io_clusterextensions.yaml to be unchanged.

Nit again, sorry: Ignore feature gates, experimental vs. standard, etc. Just plainly state what the field is/means, etc. for users of the experimental release. There should be no appearance of "when experimental is enabled" or "with the BoxcutterRuntime feature gate", etc.
Imagine this feature has been promoted to standard and it just is this way in GA. Use that description. That way when we do promote to standard, all we need to do is drop the </opcon> markers.

Generally docs start out in drafts and then we have an docs-focused community member review and move to the "main" docs.
Not sure how consistent we've been with that though. For now, I'd suggest moving to drafts, and we should then separately review our drafts and make a push for them to be moved to the main docs.

Nit: I'd suggest renaming this to something more semantic related to the feature it gates in the manifest provider rather than the feature gate we decided to put it behind.
Maybe IsNamespaceManagementEnabled, but still driven in main.go from the BoxcutterRuntime feature gate.

I wonder if experimental should just let go of this immutability and allow changes: set to unset, unset to set, and set to something else.
We imagined that we'd eventually deprecate spec.namespace and move the field to be sourced from spec.config. Now that we don't have an SA field, I'm thinking the need for immutable namespace field is now much lower, maybe non-existent.

This feels like a slippery slope to me. Why would we give special treatment to namespaces, but not any other object type that has a conflict?

Any reason we need both InstallNamespace and InstallNamespaceTemplate. Could we just have InstallNamespace *corev1.Namespace, and if all we have is a name (and no metadata), we'd just populate/read from InstallNamespace.Metadata.Name?
Otherwise, it seems like there's the awkward possibility of InstallNamespace and InstallNamespaceTemplate disagreeing on the name.

When spec.namespace is omitted, operator-controller resolves a managed namespace from bundle metadata using the fallback chain: suggested-namespace-template > suggested-namespace > -system.
The managed namespace is included as a ClusterObjectSet object with collision protection. Pod Security Admission labels from the bundle's suggested-namespace-template annotation are applied to the managed namespace, enabling operators to declare their PSA requirements
