+//! Tests cover:

+//! - Container listing with delimiter (subdirectories)
+//! - Container listing with marker/end_marker (pagination)
+//! - Container listing with limit
+//! - Symlink creation and validation
+//! - Symlink GET/HEAD following
+//! - Symlink target resolution
+//! - Symlink loop detection
