• The CLI ignores the state_dir_overwrite argument by always setting storage_path to None. You should initialize storage_path from state_dir_overwrite so overrides actually take effect.

• New cleanup logic isn’t covered by any existing tests. Consider adding unit tests or integration tests for prompt_and_cleanup, force_cleanup, and directory cleanup scenarios.

When there are no containers, the method returns early and skips cleaning task directories. Consider separating container and directory checks so directories still get cleaned even if no containers exist.

[nitpick] Default storage path logic is duplicated here and in CleanupManager::get_default_storage_path. Consider extracting this into a shared helper to reduce duplication.
