Bug: Incompatible langchain version with upgraded @langchain/community

The upgraded @langchain/community version 0.3.58 requires langchain version >=0.2.3 <0.3.0 || >=0.3.4 <0.4.0, but the project has langchain version 0.3.2 installed. Version 0.3.2 falls in the excluded range between 0.3.0 and 0.3.4, causing npm to install a separate langchain version 0.3.36 specifically for @langchain/community. This results in two different versions of langchain in the dependency tree, which can cause type incompatibilities, behavioral differences, and increased bundle size when application code interacts with @langchain/community.
