AskUserMiddleware

Middleware that provides an ask_user tool for interactive questioning.

This middleware adds an ask_user tool that allows agents to ask the user questions during execution. Questions can be free-form text or multiple choice. The tool uses LangGraph interrupts to pause execution and wait for user input.
