maple.utils.cleanup.CleanupManager

class maple.utils.cleanup.CleanupManager

Singleton manager for automatic resource cleanup.

Manages cleanup of Docker containers and custom cleanup handlers. Uses signal handlers (SIGINT, SIGTERM) and atexit hooks to ensure resources are properly cleaned up even when the program terminates unexpectedly.

The class implements thread-safe singleton pattern to ensure only one instance exists throughout the application lifecycle.
