The LangChainopen_deep_research has gone quite(last commit is ~ 3 months ago). LangChain has explicitly shifted strategy from building "single-purpose" agentic apps to building a "general harness" for agents. The LangChainblog explicitly published a post titled "Doubling down on DeepAgents," positioning it as the primary harness for building autonomous, long-running agents. DeepAgents also provide sample code for building deep research capability.

In this PR, we will transit fromopen_deep_research to the Deep Research ofDeepAgents for OPEADeepResearchAgent.
