/**
 * Dify CLI/CLI Framework/Non-Interactive 集成测试
 *
 * 用例来源：飞书文档《Dify CLI Enhanced》— Dify CLI/CLI Framework/Non-Interactive（30 条）
 *
 * 覆盖策略：
 *  - 通过 bufferStreams（isOutTTY=false, isErrTTY=false）模拟非 TTY 环境
 *  - 验证 ANSI 颜色关闭、无 spinner、JSON/YAML 输出纯净、stderr/stdout 隔离
 *  - 非 TTY 环境下命令正常执行、exit code 正确
