/**
 * Agent Structure Validation Tests
 * 
 * Purpose: Validate agent architecture and structure (no API calls required)
 * Addresses: "13 code files created, 0 test results" gap
 * 
 * What we're testing:
 * - Agent classes are properly structured
 * - Agents have required methods
 * - Agents can be instantiated
 * - Agent lifecycle methods exist
 * - Results structure is correct
 * 
 * NOTE: These are structural tests that don't require OpenAI API calls.
 * For full end-to-end testing with actual code execution, see:
 * - code-execution-validation.test.js (requires OPENAI_API_KEY)
 * - code-creation-validation.test.js (requires OPENAI_API_KEY)
