William FH 32bbe99efc chore: Support tool runtime injection when custom args schema is prov… (#33999)
Support injection of injected args (like `InjectedToolCallId`,
`ToolRuntime`) when an `args_schema` is specified that doesn't contain
said args.

This allows for pydantic validation of other args while retaining the
ability to inject langchain specific arguments.

fixes https://github.com/langchain-ai/langchain/issues/31688

Taking a deep dive here reminded me that we definitely need to revisit
our internal tooling logic, but I don't think we should do that in this
PR.

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.
