Subject: [PATCH] Delete `contrib/langchain` folder (#764)
> [!NOTE]
> **Low Risk**
> Low risk because this only removes a deprecated `contrib/langchain`
package and related metadata, with no runtime logic changes elsewhere.
>
> **Overview**
> Removes the deprecated `contrib/langchain` subtree entirely, including
its packaging metadata (`pyproject.toml`), module stub
(`langchain_arcade/__init__.py`), and project docs/build files
(`README.md`, `LICENSE`, `Makefile`, `.gitignore`).
