Blocked on upstream protobuf release.

This bump pulls k8s.io/kubectl@v0.36.1 to dodge the removed scheduling/v1alpha1 package. kubectl@v0.36.1 transitively requires google.golang.org/protobuf@v1.36.12-0.20260120151049-f2248ac996af — a pseudo-version (master snapshot) because protobuf v1.36.12 has not yet been released.

That pseudo-version stamps the generated .pb.go files with protoc-gen-go v1.36.11-devel instead of v1.36.11. CI's generate step regenerates the files, sees the version-comment drift, and fails the git diff --exit-code check.

Holding this PR until protobuf v1.36.12 ships. Once that release happens, dependabot will pick up the clean version and the regen comment will be stable.

(Verified: go list -m -versions google.golang.org/protobuf currently tops out at v1.36.11.)
