react严格模式下webglRender初始化时会报错

- OS: macOS 15.6.1 (24G90)
- Browser chrome
- Version @antv/g@6.1.28 、@antv/g-webgl@2.0.52

## Steps To Reproduce
1. 初始化一个画布
2. 创建一个圆
3. 把圆添加进画布

```ts
import { Canvas, CanvasEvent, Circle } from "@antv/g";
import { Renderer } from "@antv/g-webgl";
import { useEffect, useRef } from "react";

export function Test() {
const ref = useRef(null);
useEffect(() => {
if (!ref.current) return;
const renderer = new Renderer();
const canvas = new Canvas({
container: ref.current,
width: 600,
height: 500,
renderer,
});
const circle = new Circle({
style: {
r: 50,
fill: "#1890FF",
stroke: "#F04864",
lineWidth: 4,
cursor: "pointer",
},
});

const fn = () => {
canvas.appendChild(circle);
};
canvas.addEventListener(CanvasEvent.READY, fn);
return () => {
canvas.removeEventListener(CanvasEvent.READY, fn);
canvas.destroy();
};
}, []);

return

```
如果关闭react的严格模式不会报错，打开会报错，
报错信息如下：

Reproduce the example with React Strict Mode, then trace the cleanup path from canvas.ts and Canvas.ts through RenderingService.ts to RenderGraphPlugin.ts around line 277. Compare the initialization and destruction sequence across the repeated effect lifecycle. Done means the example no longer throws during strict-mode initialization or cleanup, while the non-strict behavior remains intact.
