Just added CI, which just runs TypeScript's typechecking for now. I've done a bit of research, and it doesn't seem that you are able to write unit tests for email workers, which is unfortunate.

almost there, just a bit of a tweak so that we dont have to spam cd's (which aren't consistent anyway)

feel free to also add prettier checks (CI) while you're at it.
it's also interesting that the starter doesn't seem to give eslint, would it be a good idea to integrate eslint/prettier or biomejs? @Zopolis4 thoughts on integrating this ci with the existing framework

I guess? It's manually installing pnpm and so on which is in contrast to the existing reviewdog-based designs, and #9 already does the same thing using (in my opinion) cleaner and simpler code, with the benefit of fancy reporting
