//! Main Integration Tests for Docker Wrapper
//!
//! This file contains cross-module integration tests and general functionality tests.
//! Command-specific integration tests are in separate files (e.g., run_integration.rs).
//! These tests require Docker to be installed and running.
//! They will be skipped if Docker is not available.
