dsh-smart-reminder: DSH Web GUI Plugin for General-Purpose Smart Reminders, Lunar Calendar Kanban, and To-Do List Assistant

`dsh-smart-reminder` is a client-side plugin that integrates reminders, calendar, and to-do lists to address fragmented information. Its core features include a top lightning quick-capture bar (with natural language parsing), automatic rescheduling of recurring tasks, OS-native notifications (with offline catch-up delivery), drag-and-drop rescheduling, and deep localization. It also supports integration with messaging ecosystems (such as WeCom and email), iCal export, and is compatible with native reminder mechanisms on macOS and Windows, significantly reducing the operational overhead of schedule management.
