Krate AgentSubagent overview

AgentSubagent defines a reusable subagent role inside an agent stack, giving Krate a Kubernetes-native way to govern specialist agent participation. It is owned by the agent-dispatch service and participates in governed agent execution. Atlas models it as a agent CRD with Namespaced scope, v1alpha1 storage version, and source-backed Kubernetes API metadata so controller, policy, UI/API, and provider edges can target the exact resource kind.
