 Lua Runner for Cangjie 是一个专为仓颉语言设计的轻量级、高性能 Lua 脚本执行引擎。它通过 C FFI 桥接 C++，提供了稳定且易用的 Lua 虚拟机管理能力。
 **注：本项目是开发原生鸿蒙应用时产生的副产物，当前版本依然存在局限性与不足，请详细检查后再使用。**
 
+安全与发布说明：仓库中不应提交任何中心仓访问令牌、私有凭据或其他敏感配置。发布前请使用本地环境变量、用户级配置或 CI 密钥注入方式提供认证信息，并检查待上传制品中不包含明文凭据。
+
 除了基础的脚本嵌入功能外，该引擎的核心特色在于支持一种独特的 **“栈式管道执行模式”**，能够实现脚本间的隐式参数传递，非常适合构建数据处理管道、游戏脚本系统或插件化架构。同时，它提供了完善的异常处理机制和灵活的 I/O 重定向功能。
 
 ## 特性
@@ -180,7 +182,12 @@ println(finalResult) // 最终输出: [PREFIX] HELLO [SUFFIX]
 - **容量限制**：内部使用固定数组管理加载的库，上限为 **20 个**，超过将报错 `5016`。
 - **I/O 性能**：I/O 重定向依赖于文件系统交换，相对于纯内存交互存在微小的性能开销。
