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. --- Closes #31325 Closes #32967 Closes #32977 Closes #32981 Closes #33643 Closes #33757 Closes #34056 Closes #34797 Closes #34962 Supersedes #33902, #34867 (thank you @elonfeng and @okamototk for your initial work on this!) --- Bugs with upstream sdk: - https://github.com/OpenRouterTeam/python-sdk/issues/38 - https://github.com/OpenRouterTeam/python-sdk/issues/51 - https://github.com/OpenRouterTeam/python-sdk/issues/52
