Walkthrough

This PR upgrades the LangChain library from version 0.0.63 to 0.1.29, representing a significant architectural shift from a monolithic package to a modular structure. The update introduces new scoped packages (@langchain/community, @langchain/core, @langchain/openai) that replace the previous single-package approach. Additionally, major dependency upgrades include @anthropic-ai/sdk (0.4.3 → 0.9.1) and openai (3.2.1 → 4.104.0). The update removes several deprecated dependencies and replaces them with modern alternatives, including transitioning from custom fetch implementations to native fetch APIs, and updating tokenization libraries. Numerous transitive dependencies are also updated to support the new modular architecture.
