/**
 * Agent Spec Default Node Types
 *
 * Provides optional starter node type definitions for the Agent Spec format.
 * These are full NodeMetadata objects with visual type, category, default ports,
 * config schema, and icon — suitable for populating the sidebar.
 *
 * These definitions are NOT required by the adapter — the adapter uses
 * componentTypeDefaults.ts for import/export infrastructure.
 * Users can provide their own node definitions instead.
 *
 * @example
 * ```typescript
 * import { getDefaultAgentSpecNodeTypes } from '@flowdrop/flowdrop/core';
 *
 * mountFlowDropApp(container, {
 *   nodes: getDefaultAgentSpecNodeTypes(), // or your own definitions
 * });
 * ```
