ExtensionDiff in renderers (just tried console and html)

I'm implementing ExtensionDiffs, but it seems they don't make it into the renderers, or at least I don't see how they would.
I.e. I'm only using console and html.

The console renderer just lists the route as changed and says there were backward incompatible changes in the spec but no further detail.

The html renderer lists the route under "What's Changed" with an empty <ul> with class detail which then renders as a thick gray line.

It would be nice if the renderers would be able to display details about the extension differences, especially when they are breaking, but also the non-breaking ones would be interesting.

In the html renderer result there is not even an indication whether there were breaking changes or not if the breaking changes come from an extension diff.

首先跟踪 ExtensionDiff 从比较输出到控制台和 HTML 渲染器的流程，重点关注现有的路由变更和详细列表渲染。完成的标准是两个渲染器都显示扩展差异的详细信息，并指出这些差异是 breaking 还是 non-breaking。
