//! Complete integration test for marketplace functionality using testcontainers
//!
//! This test demonstrates the full marketplace workflow:
//! 1. Search for packages in the registry
//! 2. Install packages from the marketplace
//! 3. List installed packages
//! 4. Use packages in actual applications
//! 5. Test with real database and cache containers
