Mason Daugherty f9fd7be695 feat(openrouter): add langchain-openrouter provider package (#35211)
Add a first-party `langchain-openrouter` partner package
(`ChatOpenRouter`) that wraps the official `openrouter` Python SDK,
providing native support for OpenRouter-specific features that
`ChatOpenAI` intentionally does not handle.

Also adds scope-clarifying docstrings to `ChatOpenAI` / `BaseChatOpenAI`
warning users away from using `base_url` overrides with third-party
providers.
