What it may solve
Update management for the whole stack: compares DeepSeek Harness and every installed third-party plugin against npm and GitHub releases (semver-aware), shows a locale-aware banner (zh/en) with per-plugin update status, and provides one-click updates with automatic backup/rollback, temp-dir installs that never touch other packages, and a watchdog-guarded restart. A settings page adds per-plugin version lamps, live update progress, and banner/notification toggles. Zero-config on any machine.
