+/**
+ * 编译期宏：从指定 cjpm.toml 读取 version 字段并替换变量声明。
+ *
+ * 用法：
+ * ```
+ * @ReadTomlVersion[path: "cjpm.toml"]            // 读取当前包（编译目录）的版本
+ * let appVersion: String = ""
+ * @ReadTomlVersion[path: "../simapi-cj/cjpm.toml"]  // 读取父包版本
+ * let simApiVersion: String = ""
+ * ```
+ *
+ * 说明：宏在编译期执行，工作目录为 cjpm build 的运行目录（应用项目根）。
+ * 版本号仅匹配 `version = "x.y.z"`（排除 cjc-version）。
