kubectx and kubens for Cluster Switching

kubectx switches contexts; kubens switches namespaces. Saves seconds per command.

kubectx

kubectx prod-east switches to that context.

Tab-completion makes it instant.

kubens

kubens default-space switches namespace within current context.

No more --namespace on every command.

Safety

Verify with kubectx (no args) to see current.

Critical for prod safety.
