+- Shell status bar renders enabled plugin `statusBarItems` contributions.
+- Items support `left`, `center`, and `right` positions. Missing position
+  defaults to `left`.
+- The host refreshes on plugin reload/enable/disable through
+  `verstak:plugins-changed`.
+- `handler` is preserved in the contribution summary for future action routing;
