        - execute(task: Any) -> Any: Attempts to execute the given task with the primary executor and falls back if necessary.

This code defines a `FallbackExecutor` class that encapsulates error recovery logic. It includes docstrings for all methods, type hints for parameters and return values, and an example usage demonstrating how to use the class with both primary and fallback executors.
