//! compact! 宏集成测试 — PHP `compact()` 一致性验证（R5 硬约束）
//!
//! 对齐 PHP `compact()` 函数行为：
//!
//! ```php
//! $code = 1;
//! $msg = "ok";
//! $data = ["id" => 1];
//! return compact('code', 'msg', 'data');
//! // 等价于：['code' => 1, 'msg' => "ok", 'data' => ["id" => 1]]
//! ```
//!
//! PHP `compact()` 关键行为：
//! 1. 接受变量名作为参数（字符串或数组）
//! 2. 在当前作用域查找同名变量
//! 3. 返回关联数组，键是变量名，值是变量值
//! 4. 字段顺序严格按参数顺序保序
//! 5. 支持任意类型的变量值
