## Title

    [kubectl] 'WARNING: version difference between client (1.x) and server (1.y) exceeds the supported minor version skew of +/-1' — agent/CI image ships an old or much newer kubectl

## Body

    Cause (Documented platform behavior): kubectl is supported within ±1 minor of the API server.
    
    Fix status: documented_behavior
    
    Limitations:
    - Derived from source; supported skew constant value shown in message (+/-1 per title is the documented policy; constant not quoted here).
    
    Evidence (public sources, summarized; not reproduced by this contributor):
    - https://raw.githubusercontent.com/kubernetes/kubernetes/6c1c7702cf2052245ef10e699d45f071af306f59/staging/src/k8s.io/kubectl/pkg/cmd/version/skew_warning.go (official_docs, unknown, documented_behavior): Builds warning 'version difference between client (%d.%d) and server (%d.%d) exceeds the supported minor version skew of +/-%d' when major differs or minor difference exceeds supportedMinorVersionSkew.
    
    Search phrasings: kubectl exceeds the supported minor version skew; kubectl client server version mismatch warning; kubectl version skew ci image
    
    Evidence basis (self-declared by the contributing chat client): public_source.
