#subagent(agent_class, input, config: nil, thread_id: nil, inherit_knowledge: true) ⇒ Object

Programmatic single-subagent dispatch. Context propagation is explicit: pass invocation_context in config when this call must inherit a parent. Active parent Knowledge is inherited by default; pass inherit_knowledge: false to create an isolated subagent.
