Normalizes raw Pydantic schemas to AutoStrategy when middleware overrides response_format. When middleware calls `request.override(response_format=SomePydanticClass)` with a raw schema, the code now wraps it in `AutoStrategy` before processing. This prevents an `IndexError` crash that occurred because raw schemas were falling through to the "no structured output" branch.

Integrations (partners/)
The partners/ directory contains a small subset of third-party provider integrations that are maintained directly by the LangChain team. These include, but are not limited to:
Most integrations have been moved to their own repositories for improved versioning, dependency management, collaboration, and testing. This includes packages from popular providers such as Google and AWS. Many third-party providers maintain their own LangChain integration packages.
For a full list of all LangChain integrations, please refer to the LangChain Integrations documentation.
