    A class for executing tasks with fallbacks in case of errors.
    
    This class allows defining a main execution function and multiple fallback functions that can be triggered
    if the primary function fails. The first available fallback is executed until one succeeds or all are exhausted.
    
    Attributes:
        main_func (Callable): The main function to execute.
        fallbacks (Dict[str, Callable]): A dictionary of fallback functions with unique names as keys.
        current_fallback (Optional[str]): Keeps track of the currently executing fallback.
        
    Methods:
        run: Executes the main function or one of its fallbacks if an error occurs.
