Description

RTK only registers a BeforeTool hook on run_shell_command. But when Gemini CLI uses --yolo to read files, it uses the read_file tool

Can we extend rtk to hook into read_file also?

Research direction
Investigate the existing BeforeTool hook implementation in the rtk codebase, specifically for run shell command. Understand how tools are registered and how hooks are invoked. Then, implement a similar hook for the read file tool, ensuring it follows the same pattern. Check existing tests and documentation for guidance.
