/**
 * 轻量级 VueFlow 兼容层
 *
 * 用途：在移除 @vue-flow/core 依赖后，仍保留 Handle / Position / ConnectionMode
 * 的 API 表面，使现有节点组件只需替换 import 路径即可继续工作。
 *
 * 数据结构保持 VueFlow 兼容：
 * - 节点：{ id, type, position: {x, y}, data, selected?, class? }
 * - 边：  { id, source, target, label?, labelStyle?, type?, style?, data?, animated? }
 *
 * 这样后端接口（flowContent JSON）无需变更。
