[Bug]: create-edge.ts mode.translateNodeTo该方法参数应该转化为canvas坐标。

### Describe the bug / 问题描述

这里应该将浏览器坐标转换为canvas坐标
```javascript
model.translateNodeTo(ASSIST_NODE_ID,[event.client.x,event.client.y]);

//fixed
const [cx,cy] =graph.getCanvasByClient(,[event.client.x,event.client.y]);

```

Start in create-edge.ts and inspect the mode.translateNodeTo call shown in the issue, along with the graph coordinate-conversion API. Confirm whether the event values are browser coordinates and whether they must be converted before moving ASSIST_NODE_ID. Done means the node movement uses canvas coordinates and the existing behavior remains correct across the listed browsers.
