/**
 * Todo Example Plugin
 *
 * Exports the Todo configuration as an ObjectStack plugin that can be
 * loaded by any ObjectStack application. Other projects can import
 * the Todo metadata (objects, apps, dashboards, manifest) without
 * needing to know the internal structure.
 *
 * Usage in another project:
 *
 *   import { TodoPlugin } from '@object-ui/example-todo/plugin';
 *
 *   const kernel = new ObjectKernel();
 *   kernel.use(new TodoPlugin());
 *
 * Or import the raw config for merging:
 *
 *   import { todoConfig } from '@object-ui/example-todo/plugin';

 * Todo Plugin — wraps the Todo metadata as a kernel-compatible plugin.

 * will register all Todo objects, apps, dashboards, and seed data.
