dsh-lark-meeting-notifier: View and remind Lark meetings in the DSH workspace

dsh-lark-meeting-notifier is a DeepSeek Harness (DSH) plugin designed to address the issue of users easily missing Lark meetings while working in the DSH workspace. The plugin displays a floating box on the right side of the workspace, listing today's remaining meetings along with their meeting room names. It uses a multi-alarm mechanism to trigger flashing reminders as meetings approach, with colors changing based on urgency. Users can click on an entry to dismiss the reminder or permanently remove the local reminder. It also supports viewing tomorrow's meetings, and all operations only affect local reminders without modifying the original data in the Lark calendar. Before installation, ensure that `lark-cli` has been authorized for user-level calendar read access, and configure the `danger-full-access` sandbox policy when executing within the Host. The plugin offers configurable options, including advance reminder times and automatic stop functionality.
