Overview

Encapsulates cluster context (name, config, client) to reduce boilerplate in command implementations.

Instead of repeating:

cluster = ClusterValidator.get_cluster(options[:cluster])
cluster_config = ClusterValidator.get_cluster_config(cluster)
k8s = ClusterValidator.kubernetes_client(options[:cluster])

Use:

ctx = ClusterContext.from_options(options)
# Access: ctx.name, ctx.config, ctx.client, ctx.namespace
