开启workspace之后ctx的project拿不到simulotar对象

## 开启workspace之后想通过ctx.project 分别import各个window的schema然后切换window的时候ctx.simulatorHost.render()直接渲染.但是发现ctx下面的project为null,所以想知道 workspace和project的关联。 workspace有无文档或者说明之类的官网只有api看着有点蒙。

Start by reviewing the workspace and project API documentation and the relationship described in the issue. Trace the documented workspace and project entry points and verify how ctx.project behaves after workspace is enabled. Done means the relationship and supported access to each window's schema are clearly documented.
