@swxs/archive-restore: DSH Archive Session Management Plugin

`@swxs/archive-restore` is a plugin designed for DSH to address the issue of archived sessions being ignored in the main view. It provides a Web sidebar entry, allowing users to view the archive list, search and filter by title or workspace, and click an icon to restore an archived session to its original location while preserving the seat. The plugin only modifies the archive ledger, does not touch session logs, and the data remains retained after uninstallation. After installation, restart the Web client to start using it.
