Preview link: https://docs-git-mateo-dev-141-update-langchain-quicks-7f4cdb-arcade-ai.vercel.app/en/get-started/agent-frameworks/langchain/use-arcade-with-langchain-py

This PR adds a Python version of the LangChain tutorial that features

  • Transforming Arcade tools into LangChain
  • Building an Agent with the latest version of LangChain
    all without relying on the old langchain-arcade package

Note

Low Risk
Low risk documentation-only changes, but redirects update multiple legacy LangChain URLs and could break inbound links if misconfigured.

Overview
Adds a new Python LangChain quickstart (use-arcade-with-langchain-py) that demonstrates converting Arcade tool schemas into LangChain StructuredTools and handling Arcade authorization via LangGraph interrupts.

Updates LangChain navigation metadata to split the tutorial into Python and TypeScript entries, and expands next.config.ts redirects so old LangChain tutorial URLs (including the prior use-arcade-with-langchain path) now permanently route to the new Python page. Also refreshes public/llms.txt to reference the new LangChain Python/TS pages.
