//! End-to-end integration tests for AI commands
//!
//! **Chicago TDD Principles**:
//! - REAL CLI process execution
//! - REAL API calls (when available)
//! - REAL state verification
//! - NO mocking of AI responses
//!
//! **Critical User Workflows (80/20)**:
//! 1. Generate code with AI assistance
//! 2. Interactive AI chat session
//! 3. Analyze code and provide insights
//!
//! NOTE: AI commands are currently stubbed pending domain refactoring.
//! These tests verify CLI interface works correctly.
