Create a minimal, extensible CLI for the config generation tool. This will serve as the user interface for triggering config generation and, later, for managing NUMA/topology logic.

Description:
Develop a basic command-line interface (e.g., using argparse or similar) that allows users to:

• Run the config generation process with arguments such as input template path, output directory, and run-specific parameters

• Print usage/help text

This ticket is only for scaffolding and essential user input handling.
