- 运行器新增 language-server 模式：常驻语言服务，和编译服务分开；用 Roslyn 的
CompletionService、QuickInfoService（和 VS 的 IntelliSense 同一套引擎），参数提示用语义模型实现；
每个浏览器标签页一份工程，只更新有变化的文件；去掉仿真类库的可空注解（string? → string）
- 编译和语言服务共用同一套编译选项和引用；检查结果带上禁止 API 的报错和中文提示
- 服务端 POST /api/language 转发请求（按用户区分会话，10 秒超时）
- 编辑器：补全（"." 触发，选中时取说明）、悬停、参数提示（"(" "," 触发）；停止输入 1 秒后检查整个工程，
和"运行"时的编译结果以较新的为准
- 实测（2 核）：50 个标签页同时检查 1.2 秒内完成，同时补全 0.7 秒；内存约 260 MB
