 * 验证一个由 Pipeline 生成的项目中：
 *   1. Schema 字段 100% 匹配 Contract 定义
 *   2. Types 字段名（camelCase）100% 匹配 Contract 的 fieldMapping
 *   3. Routes 的 DTO 类型 100% 匹配 Contract
 *   4. Services 的 SQL 列名 100% 匹配 Contract
 *   5. Tests 使用的字段名 100% 匹配 Contract
 *
 * 验证失败则 exit(1)，成功 exit(0)。
 * 输出 contract-consistency-report.md。
