Is it possible to render SPA apps using a server handler

[barelyhuman]

Wanted to figure out if something like this was a part of the scope .

Repro: https://github.com/barelyhuman/vinxi-spa-custom-server-repro

Use Case

An SPA app (basically no server side work) but we wish to have the entry point be ./src/app.html for the framework's consistency.

To add that since the spa type allows a nitro handler, the dev version of the above works as expected but then build fails since there's no index.html and it depends on it's existence
