feat: add command-line interface and package management functionality

- Implemented a new CLI using Clap for managing Fedora configurations and packages.
- Added commands for configuring dnf, adding repositories, installing RPM Fusion, adding users to groups, and managing packages.
- Created data files for various package lists (AMD, Intel, common, firmware, gnome extra) and user groups.
- Introduced Zsh completion script for improved command-line usability.
- Removed the old CLI implementation and integrated the new structure into the main application logic.
