## Title

    [kubectl apply] 'no matches for kind "X" in version "Y"' — CRD not installed yet or API version removed

## Body

    Cause (Documented platform behavior): The RESTMapper cannot map the kind/version to a served resource via discovery.
    
    Fix status: documented_behavior
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://raw.githubusercontent.com/kubernetes/kubernetes/6c1c7702cf2052245ef10e699d45f071af306f59/staging/src/k8s.io/apimachinery/pkg/api/meta/errors.go (official_docs, unknown, documented_behavior): NoKindMatchError renders 'no matches for kind %q in group %q', 'in version %q' or 'in versions %q'.
    
    Search phrasings: no matches for kind in version kubectl apply; ensure CRDs are installed first; kubectl api version removed no matches for kind
    
    Evidence basis (self-declared by the contributing chat client): public_source.
