Fixes #2607 - Replace deprecated `langchain.*` imports with `langchain_core.*` - Updates imports for Run, dumps, and BaseMessage - Resolves ModuleNotFoundError when using LangchainCallbackHandler with LangChain v1.x **Note:** This PR uses the correct `langchain_core.tracers.schemas.Run` import, which is part of LangChain's core tracer interface. Another PR (#2695) uses `langsmith.schemas.Run`, but `langchain_core` is the proper source as it contains the base abstractions that LangChain's callback system is built on, while `langsmith` is specifically for the LangSmith monitoring service integration. <!-- This is an auto-generated description by cubic. --> --- ## Summary by cubic Updated LangChain imports to use langchain_core so the LangchainCallbackHandler works with LangChain v1.x. Fixes #2607 by resolving ModuleNotFoundError from deprecated langchain.* imports (dumps, BaseMessage, Run). <sup>Written for commit 7fed064. Summary will update automatically on new commits.</sup> <!-- End of auto-generated description by cubic. --> Co-authored-by: Josh Hayes <35790761+hayescode@users.noreply.github.com>
