This PR introduces the concept of a tool registry. The implementation is straightforward: you can define a tool by creating a class with a function name. The function name gets registered in the registry and can be referenced during LLM calls. When the LLM invokes a tool using the registered name, the registry locates and executes the appropriate tool. If the LLM calls an unregistered tool, the registry returns an error indicating that the tool is not defined.
