[F1] @vue-flow/core 依赖 + DagCanvas 基础组件
- apps/web-antd/src/components/iot-dag/ 7 文件
- DagCanvas.vue / DagCanvasToolbar.vue
- hooks/useDagState.ts（50 步撤销栈 + structuredClone 深拷贝）
- hooks/useDagShortcuts.ts（Del/Ctrl+Z/Ctrl+Y + input guard）
- types.ts（DagNode/DagEdge/DagCanvasProps + 6 emits）
- index.ts barrel + __tests__/DagCanvas.spec.ts（16 用例全绿）
- pnpm-workspace.yaml: catalog 新增 @vue-flow/{core,background,controls,minimap}
- apps/web-antd/package.json: 4 包全部 'catalog:' 引用
- i18n: zh-CN/en-US iot.dag.toolbar.* + iot.dag.canvas.* 同步
- Known Pitfalls 落地: ⚠️ catalog 约束 / 样式 import / TS 严格零 any
note: Acceptance #7 (Storybook/playground) 项目未集成 Storybook,
