[Feat]: `brush-select`交互应该增加一个能拦截清空元素状态的配置

### Describe the feature / 功能描述

当自定义一些其他交互时，单击画布空白区域，很有可能需要保持元素状态。
但是如果同时启用了brush-select，而brush-select中，点击画布空白区域，默认会清空所有元素的状态。

Start by locating the TypeScript implementation of the `brush-select` interaction and inspect how a blank-canvas click clears element state. Check for existing interaction configuration tests or examples before deciding how the option should behave. Done means the new configuration can prevent clearing while the default behavior remains unchanged.
