/**
 * OpenAPI Path Validator
 * 
 * Basic smoke test to verify all OpenAPI paths are reachable.
 * Does NOT replace proper API testing!
 * 
 * For comprehensive testing, consider:
 * - Dredd (npm install -g dredd) - Contract testing against OpenAPI spec
 * - Postman/Newman - Import openapi.json and run automated tests
 * - Prism (npm install -g @stoplight/prism-cli) - Mock server + validation
 * - Jest/Supertest - Full integration tests with schema validation
 * 
 * This script only checks if paths respond (basic reachability check).
