Add support for LangGraph Framework

[datlaphani]

Request to add support for monitoring and tracing the LangGraph framework. This will enable tracking key performance metrics, troubleshooting issues more effectively, and improving overall system observability when integrating LangGraph-based operations.

As we continue to leverage graph-based natural language processing (NLP) and graph neural networks (GNNs), it becomes critical to understand how the LangGraph framework performs, especially regarding latency, GPU utilization, error rates, and graph query execution. By incorporating monitoring and tracing capabilities, we can ensure the LangGraph operates efficiently and scales with growing data and user needs.
