Vitest fixes

[Duddino]

Abstract

Vitest occasionally segfaulted. According to the docs, we were using the default multi threaded pool,

Enable multi-threading using tinypool [...] some libraries written in native languages, such as Prisma, bcrypt and canvas, have problems when running in multiple threads and run into segfaults. In these cases it is advised to use forks pool instead.

This PR changes the pool to fork, which should not have this issue. This incurs approximately a 10% decrease in performance.

Additionally, a setup file was added where we setup the happy-dom environment with the correct skeleton, instead of doing it each time per test.

Testing

Run npm test a bunch of times, and check that it doesn't segfaut
