    A dataclass for holding command line arguments in the Pynenc CLI.

    This class is a custom namespace for parsing command line arguments using `argparse`.
    It extends the functionality of `argparse.Namespace` by explicitly defining fields for
    expected arguments. This approach enhances code clarity and type-checking.
