/**
 * 通知渠道集成模块
 *
 * 对外导出:
 * - sendNotification / sendBatchNotifications: 分发器入口
 * - createNotification / getNotifications / markNotificationAsRead / markAllNotificationsAsRead / getUnreadNotificationCount: 站内通知 CRUD
 * - getNotificationPreferences / upsertNotificationPreferences: 通知偏好 CRUD
 * - 类型定义: NotificationPayload, ChannelSendResult, NotificationChannel, NotificationType, Notification, NotificationPreferences 等
 * - 渠道发送器工厂: createSmsSender, createWechatSender, createEmailSender, createInAppSender
 *
 * 典型用法:
 * ```ts
 * import { sendNotification } from "@/modules/notifications"
 * await sendNotification({
 *   userId: "user-xxx",
 *   title: "作业提醒",
 *   content: "您有一份新作业待提交",
 *   type: "info",
 *   actionUrl: "/homework/123",
 * })
 * ```
