Description

背景

ProjectSchema.config在我的实际需求中会比较容易变化。

之前的方案是修改ProjectSchema,再用project.importSchema去更新，并用project.onChangeDocument去监听变化，但是这种方案会引发https://github.com/alibaba/lowcode-engine/issues/1122 问题。 官方没对这个api没有很清晰的描述，我只能假定该方法只适合初始化是调用。于是改成,project.setConfig方式修改config。但这个api无法被监听。

Research direction
The issue requests a way to listen to changes in ProjectSchema.config, as the current workaround using project.setConfig is not observable. To implement, one would need to explore the lowcode engine's event system, likely in files like packages/engine/src/modules/project.ts or similar. Look at how project.onChangeDocument is implemented and replicate a similar pattern for config changes. The assignee may have started work; check comments for any updates.
