dsh-approval-reminder: Persistent Approval/Issue Reminders for DeepSeek Harness

`dsh-approval-reminder` is a DeepSeek Harness plugin designed to address the issue of approval/confirmation requests being easily and silently missed in a Web GUI. It uses a persistent system bubble in the bottom-right corner and in-page reminder cards to ensure that users do not overlook pending interactions. The plugin adopts a dual-end architecture, leveraging PowerShell/WinForms to render the bubble on the host side while monitoring session state on the browser side. It supports Windows only, provides lossless Chinese transmission, and requires files to be placed in a specified directory and the plugin ID to be enabled in the configuration file; the service must be restarted after configuration changes.
