This PR only updates @langchain/core in the example directory but misses updating the same dependency in the root package.json file (line 47), which is currently at version ^0.3.26. The security vulnerability affects both locations, so the root package.json should also be updated to version ^0.3.80 to ensure the vulnerability is fully addressed across the entire project.
