We've been dogfooding setup-launch-node-server and our global browser vitest setup in browser tests for some time now and haven't had any problems with it, so we can expose it to our users as well.

To finish this, we'd have to expose setup-launch-node-server, possibly as a CLI utility, as well as write some docs on how the test setup should be done. Inspiration for the docs can be taken from vitest.global-browser-setup.ts.
