refactor: Restructure CLI File Organization and Update Includes

- Updated CMakeLists.txt to reflect new file paths for CLI components, enhancing project organization.
- Replaced instances of the deprecated z3ed.h with cli.h across multiple handler files, improving code consistency and maintainability.
- Organized CLI source files into a dedicated directory structure for better modularity and clarity.
