feat(permissions,clients,ai,system,server,web,client,shared)!: 权限组 + 客户端设备远控与自动更新 + 大模型助手 + 系统诊断（1.3.0）
功能级准入改为「权限键」，`requireRole` 退成默认模板。 权限组 - 权限目录（39 键：键 / 中文名 / 分类 / 默认角色）收口到 shared，路由挂 requirePermission / requireAnyPermission - 有效权限每请求实时算，改完分组立刻生效：ADMIN 全集且 permission:manage、system:manage 不可剥夺； CLASS_DEVICE 空集（不受分组影响）；有分组 = 并集（因此也能用来**收回**权限）；无分组 = 角色默认模板 - 新增「权限组」页：组增删改、成员分配、生效权限预览 - 班级维度的科目规则（assertCanManageSubjectContent）故意不可被权限组覆盖 客户端设备（ClassHelper 桌面端） - 设备身份是 deviceKey（首次启动生成的 UUID，saveConfig 拒绝改写、退出登录也保留） - 心跳走「DB 记状态 + 客户端定时拉」，不引入新的长连接：30 秒一次，在线窗口 90 秒 - 远控命令 shutdown / restart / logoff / lock：服务端有效期 10 分钟，客户端弹默认选中「取消」的对话框、 60 秒未确认按取消处理，执行后必须回执（重复回执幂等），同一台机器同一条命令只弹一次 - 新增「客户端设备」页：版本一览、一键推送更新、下发远控 客户端安装包由服务端下载并缓存（教室机常常没有外网，浏览器也受 CSP 限制） - POST /api/update/client/fetch 由服务端下载到 data/client-releases/<版本>/ 并登记 sha256 + size - 自动安装三条护栏：没有 sha256 就拒收、必须等到非上课且主窗口隐藏满 5 分钟、冒烟模式永不安装 大模型助手：只解析、不落库 - POST /api/ai/interpret 返回**待确认**的结构化动作（建作业 / 发通知 / 叫人）， 真正落库仍调既有端点 —— 权限断言、上课时段紧急通知保护、ClassIsland 推送全部自动复用 - 模型给的 params 用与手动入口**同一份** zod 再校验（模型输出不可信） - API Key 走 AES-256-GCM（密钥由 JWT_SECRET 经 scrypt 派生）加密存 AppSetting，只进不出 - provider=mock 是离线确定性解析，自动化验收一律用它；每次解析写一条 AiAudit（不含密钥） 系统与运维 - 开发者模式（服务端内存缓存开关，热路径不查库；开启后 500 才附 error.stack）、运行诊断（绝不回传密钥） - 开机自启动运行期可改：Windows 改 HKCU\...\Run、Linux systemctl enable/disable， **非安装形态一律返回 supported:false**，不往开发机的注册表里写自启项 - 服务端侧栏折叠只用 CSS 收拢（不重建 DOM），关怀模式只放大字号与控件、不动任何几何令牌 客户端 - 崩溃自愈：渲染进程挂掉 / 超 10 秒无响应先静默重建主窗口（10 分钟最多 3 次）， 未捕获异常只在「没在上课、没人看着」时才重启进程；冒烟模式绝不重启（会杀掉验证实例） - 上线补弹离线期间收到的消息只做一次：起点只在「可达 → 不可达」的边界写，恢复时取最近 5 条按时间升序推 发布内容批量 - POST /notifications/bulk、POST /homeworks/bulk：**单班失败不影响整批**，逐班返回结果 - 作业的科目名跨班**按名匹配**已有课程，找不到就整班记失败，绝不自动建课 （自动建课会把创建者写成任课老师，等于越权改任教关系） - 通知与作业同口径按「所属日期」归档，新增 /notifications/days 与 /notifications/creators BREAKING CHANGE: 能不能做某件事不再看角色名，而是看权限键（GET /api/permissions/me）。 未分组的账号按角色默认模板生效，行为与 1.2.0 一致；分组之后生效集合只由组的并集决定。 服务端首次启动会自动应用 1 个数据库迁移（权限组 3 表 / AppSetting / 客户端设备·命令·安装包 / AiAudit / Notification.assignDate / User.careMode，历史通知按本地日期回填），升级前请先备份。
