📦 chore: Patch axios to address CVE-2025-27152

[danny-avila]

Summary

I updated the axios dependency across multiple package files to address CVE-2025-27152 and removed the unused langchain package from the API to clean up the repository.

• Bumped axios in api/package.json from 1.7.8 to ^1.8.2.
• Upgraded @langchain/community in api/package.json from ^0.3.14 to ^0.3.34.
• Added an axios override in the main package.json for version consistency.
• Removed the langchain dependency from api/package.json since it is no longer used.
  • @langchain/community still uses the latest version of the now deprecated langchain dependency

Testing:

• Ran npm install and verified that all package versions resolve correctly.
• Executed local unit tests to confirm that no new warnings or errors are present.
