Previously, kubectx would error with "multiple files in KUBECONFIG are currently not supported" when KUBECONFIG contained colon-separated paths. This is a common setup where users maintain separate kubeconfig files for different clusters/environments. This change evolves the internal Kubeconfig struct from holding a single file to a slice of file entries, matching kubectl's merge semantics: - Reading current-context: first file with a non-empty value wins - Writing current-context: always written to the first file - Listing contexts: merged from all files, first occurrence wins for duplicate names - Modifying a context (delete/rename/set-namespace): written to the file that owns that context - Missing files in the KUBECONFIG list are silently skipped (matching kubectl behavior), but permission errors are propagated The Loader interface already returned []ReadWriteResetCloser, so all public method signatures remain unchanged — zero modifications needed in cmd/kubectx/ or cmd/kubens/ callers.
