/**
 * ClassIsland 联动插件静态校验：`pnpm verify:classisland-plugin`
 *
 * 为什么是"静态"校验：插件要跑起来必须有 ClassIsland 本体，而本机（以及 CI）都没有，
 * 所以这里校验"装不上 / 对不上"的那几类问题 —— 它们不需要运行就能发现：
 *
 *   1. 清单三件套一致性：manifest.yml ↔ csproj ↔ 代码里的版本号；
 *   2. 注册完整性：插件入口、提醒提供方、设置页是否都挂上了（挂漏了功能会"静默消失"）；
 *   3. **接口契约**：C# DTO 的 JSON 字段名 ↔ 服务端路由 / 请求字段，
 *      这类错误（比如 dayOfWeek 写成 dayofweek）在运行时只会表现为"上报成功但课表是空的"，
 *      最难排查，所以专门盯住。
