Upgrade langchain to 0.1.29 without API migration breaks build

Bumping langchain to ^0.1.29 pulls in the new 0.1.x release where provider code was split into packages like @langchain/openai and @langchain/community; the old entrypoints langchain/llms/openai, embeddings/openai, vectorstores/hnswlib, and document loaders are no longer exported. The current code still imports those paths (e.g., src/index.ts lines 3–14 and src/lib/contextManager.ts lines 3–13), so installing dependencies and running the app will fail immediately with module-not-found/compile errors. Either revert to 0.0.x or migrate the imports and add the new packages before upgrading.
