+- **Extensible Category System**: `NodeCategory` is now an open string type, allowing custom categories beyond the built-in set
+  - Built-in categories remain available as typed suggestions via `BuiltinNodeCategory`
+  - New `/categories` API endpoint returns category metadata (name, label, icon, color, weight)
+  - Categories are fetched at initialization and stored in a Svelte store with built-in defaults as fallbacks
+  - New `defaultCategories` config provides built-in category definitions with icons, colors, and sort weights
+  - `NodeSidebar` now derives grouping from the categories store instead of hardcoded logic
