Pull Request Overview
This PR fixes documentation for LangChain middleware by updating the tool handling specification. The main change is that ModelRequest now expects a list of tool names (strings) instead of tool instances, and adds documentation about static properties that middleware can define.
Key changes:
- Updates ModelRequest.tools type from list of BaseTool instances to list of strings (tool names)
- Documents static properties (name, tools, state_schema, context_schema) that middleware can define
- Updates all code examples to use tool names instead of tool objects
