    A class for executing tasks with limited error recovery capabilities.

    Attributes:
        default_handler (callable): The fallback handler to be used when a task fails.
        max_retries (int): Maximum number of times the task can be retried before giving up.

    Methods:
        run_task(task, *args, **kwargs):
            Executes the given task with error recovery if it raises an exception.
