Sydney Runkle 668e814027 fixup: drop state_keys= call, bump langgraph branch pin
Paired langgraph PR no longer takes state_keys — ToolNode now reads the
full channel state via CONFIG_KEY_READ internally. Revert create_agent's
factory to its original state schema resolution location and drop the
state_keys argument.

Lockfile updated to the latest commit on sr/tool-call-no-state-inline.

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.
