can't use '.' as the no active context is set

Error message

can't use '.' as the no active context is set

What it means

Validation error in deleteContext: the user passed '.' (meaning 'delete the current context'), but GetCurrentContext() returned an empty string, so there is no active context to resolve '.' against. The sentinel guard fires because '.' is only meaningful when current-context is set in the kubeconfig.

Solutions

1. Set a current context with `kubectx <NAME>` before using `kubectx -d .`
2. Delete the target context by its explicit name instead of '.'
