P1 Badge Keep langchain-core compatible with langgraph

This bump makes backend/pipeline/requirements.txt unsatisfiable: the published metadata for langgraph==1.2.9 requires langchain-core<2,>=1.4.7, but this requirements file still pins langchain-core==1.4.0 on the next line. Any fresh install or the security-audit workflow's pip-audit matrix entry for this file will fail dependency resolution before the pipeline can run, so the core pin needs to be updated with the LangGraph bump.
