+// TestJuiceFSEngine_deleteFusePersistentVolumeClaim tests the deletion logic for Fuse-type PersistentVolumeClaims (PVCs) in JuiceFS Engine.
+// It validates:
+//   - Proper handling of PVC finalizers (e.g., kubernetes.io/pvc-protection)
+//   - Failure scenarios when Runtime integration is disabled
+//   - Interaction with mocked Kubernetes API using fake client
+// 
+// The test suite includes two primary cases:
+// 1. Normal deletion with Runtime enabled (expected success)
+// 2. Deletion failure when Runtime is disabled (simulates missing dependency)
+// 
+// Setup steps:
+// - Creates test PVCs with protection finalizer to simulate real-world conditions
+// - Uses deep copies to ensure test data isolation
+// - Configures fake client with predefined test objects for controlled testing
+// - Exercises both enabled/disabled Runtime engine variations
+// 
+// This test ensures JuiceFS Engine correctly handles PVC lifecycle operations while respecting Kubernetes resource protection mechanisms.
