feat(integrations,classisland,server,web,desktop): ClassIsland 联动插件——上报课表与上课状态、下发提醒并回执、教室端推送通道
教室机器上的 ClassIsland 现在可以直接和班级小助手互通:插件走 /api/integrations/classisland/*,用设备令牌(X-ClassIsland-Token,库里只存 sha256)独立鉴权,不占用 JWT 通道。 - 服务端:新增 integrations 模块(上报 / 待弹出 / 回执 / 课表镜像 / 回写),两个迁移(设备令牌表、Class.notificationChannel);通知、叫人、联动页下发统一复用 pushToClassIsland,避免"某个页面发的通知不联动" - 插件:packages/classisland-plugin(.NET 8,独立于 pnpm workspace)——BridgeService 上报与提醒轮询、ScheduleMapper/ClassPlanWriter 课表镜像、Avalonia 设置页、ClassHelperNotificationProvider 在 ClassIsland 上弹出提醒;本地/内网地址强制直连,躲开系统代理返回的假 404 - 客户端:设置页可选提醒通道(both / client / classisland),并订阅相应实时事件 - Web 端:新增「ClassIsland 联动」页(设备管理与提醒下发) - 校验与打包:verify:classisland(需后端)、verify:classisland-plugin(静态契约 54 项)、build/dist:classisland-plugin 产出 .cipx - 文档:README 与 AGENTS.md 同步新增联动说明,docs/screenshots/classisland 留三张真机截图 门禁:pnpm lint 0 error、pnpm typecheck 四包通过、verify:classisland-plugin 54/54 通过。运行期仍需在装了 ClassIsland 的机器上实测(步骤见 AGENTS.md §8)。

/**
|

* 联动设备的令牌工具。
|
||||
*
|
||||
* 为什么不用 JWT:
|
||||
* - 令牌是「设备级长期凭证」,插件装在教室机器上,长时间无人值守,
|
||||
* 需要一个"管理员在 Web 端点了重置才失效"的凭证,而不是有固定过期时间的会话;
|
||||
* - 明文只在创建/重置接口返回一次,服务端只存 sha256 —— 库被读走也无法反推出可用令牌。
