[QDyanbing]

说明

• 保留 children={0}，不再将其当作缺少子节点而丢弃或输出错误提示。
• 使用共享 isReactRenderable 并补充回归测试；将 @rc-component/util 最低版本提升到 ^1.13.0。

验证

• npm test -- --runInBand（4 项通过）
• npm run tsc
• 改动源码 ESLint 检查通过。

关联 ant-design/ant-design#59193

MutateObserver 现在使用 isReactRenderable 判断子节点是否可渲染。新增测试验证子节点 0 会被渲染，且不会触发 console.error。@rc-component/util 的版本范围从 ^1.11.1 更新为 ^1.13.0。
