M1: 桥引擎单测代码（T-M1-08，运行待工具链）
- entry/src/test/Bridge.test.ets：13 用例覆盖 MessageCodec(toJson省略/response/escape转义/toArray)、 HandlerRegistry(put/get/默认兜底不抛错)、 BridgeController(入站分发+回执/出站callHandler/启动队列补发/ responseId回执路由/未注册名默认兜底) —— 用 FakeWebController 纯逻辑、不依赖设备 - 接入本地单测入口 List.test.ets - ⚠ 运行受阻：devecocli 无 test 子命令，本地单测 hvigor task 未常规暴露， 待定运行方式（DevEco IDE / CI / 其他）后跑覆盖率（目标 ≥80%） Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
