//! End-to-end integration tests for marketplace workflow
//!
//! **Chicago TDD Principles**:
//! - REAL CLI process execution
//! - REAL file system operations
//! - REAL template rendering
//! - REAL state verification
//! - Minimal mocking (only network calls if needed)
//!
//! **Critical User Workflows (80/20)**:
//! 1. Search marketplace for templates
//! 2. Add gpack from marketplace
//! 3. Generate project from installed template
//! 4. Remove gpack
//! 5. List installed gpacks
