//! Tests for cleanup functionality (Task 023)
//!
//! These tests verify that `SmokeModuleTest` properly cleans up temporary files and directories
//! upon completion, regardless of success or failure (FR-7).
//!
//! ## TDD Approach
//! These tests are written FIRST and will initially FAIL, demonstrating
//! the need for enhanced cleanup implementation in Task 024.
