I noticed a difference in LangSmith tracing between langgraph up and a standalone Python script using AsyncPostgresSaver + create_deep_agent. With langgraph up: reasoning_content appears in LangSmith traces With standalone Python: only message.content is traced, reasoning is not visible Both write correctly to Postgres checkpoints — I verified this in the database directly. Is this expected behavior, or is there a way to get the same tracing in standalone mode?
