dsh-archived-panel: View and manage archived sessions in the DeepSeek Harness sidebar

dsh-archived-panel is an MIT-licensed community plugin developed for DeepSeek Harness (DSH), designed to provide a unified entry point for archived session management within the sidebar. The plugin supports viewing and reopening archived sessions in the Web Profile; this functionality is available immediately after installation without requiring modifications to the DSH source code. Additionally, the plugin includes advanced features: if the host environment supports `unarchiveSession` or `deleteSession`, users can perform unarchiving or permanent deletion operations. The deletion process includes a secondary confirmation and a protection mechanism for active sessions. If the host environment has not installed the necessary patch, the plugin automatically hides these operation buttons to ensure that core functionality remains unaffected. Installation requires compatibility with DSH >= 0.1.0.
