+ * dsh-wb-sidebar — WorkBuddy/Tutti-style sidebar enhancement for
+ * DeepSeek Harness Desktop.
+ *
+ * Host-side entry (Node). This half is deliberately minimal: the real value
+ * lives in the client bundle (lib/client.js) which registers the Tasks /
+ * Agents / Profile tabs through dsh-better-sidebar's ctx.betterSidebar
+ * service. The host half exists so the bundle has a Node row to mount (the
+ * dsh.client.inject declaration in package.json pulls the browser half in).
