//! End-to-end integration tests for utils commands
//!
//! **Chicago TDD Principles**:
//! - REAL CLI process execution
//! - REAL system checks (Rust, Cargo, Git)
//! - REAL environment inspection
//! - NO mocking of system state
//!
//! **Critical User Workflows (80/20)**:
//! 1. Run system diagnostics (doctor)
//! 2. Check environment variables
//! 3. Verify tool installation
