+Integration tests for clean_dataset_task using testcontainers.
+
+This module provides comprehensive integration tests for the dataset cleanup task
+using TestContainers infrastructure. The tests ensure that the task properly
+cleans up all dataset-related data including vector indexes, documents,
+segments, metadata, and storage files in a real database environment.
+
+All tests use the testcontainers infrastructure to ensure proper database isolation
+and realistic testing scenarios with actual PostgreSQL and Redis instances.
