hulibuld/dsh-refresh-restart

Adds two buttons beside the sidebar toggle at the top-left of the DSH desktop UI, on macOS, Windows and Linux. Reload refreshes only the UI layer while a turn already generating keeps running; restart asks for one confirmation, quits the whole app and reopens it with sessions and workspaces intact. Restart is a POST that must carry a random per-boot token read from the plugin's status route. The plugin makes no network calls, reads no session content and has zero runtime dependencies.
