Prerequisites: install conductor-python[langgraph] and keep recoverable
graph nodes free of process-local state.
Install conductor-python[langgraph] and pass a supported LangGraph graph to
AgentRuntime. The bridge executes graph work through the durable runtime and
preserves streaming and human-task integration where the graph exposes it.
Start with the LangGraph examples. Avoid closures and process-local state in nodes that must run after recovery.
Expected result: graph work and emitted events are recorded in a durable Conductor-agent execution. Next: read streaming.
