run `yew` from within the `chat` application?

[tjdevries]

Can we run them from the same process? Can we start up something like axum or some other http server and use that in combination with wasmpack?

cc @davidbegin since that could make running the application a lot easier (and I wonder if we could reduce serialization because they could pass directly between the process, rather than serializing)
