Migrate to Bun

[matvp91]

Native TypeScript support sounds nice, there's no need for a transpilation step anymore.

• Slightly different from ts-rest but all bells and whistles are there, request validation, routes, plugins, ...
• There's support for OpenAPI, see https://elysiajs.com/plugins/swagger
  • A /swagger endpoint is available and embedded directly into the dashboard, it uses scalar, which we use already.
• There's support for standalone build compilation, which would allow us to provide a binary of artisan.
• A client with type support: https://elysiajs.com/eden/overview.html
• We can move away from zod and use TypeBox instead! 🎉

Remarks

• What about BullMQ? There's an issue open, Make BullMQ Compatible with Bun taskforcesh/bullmq#2177, but I'm not sure what the state is. Theoretically, Bun is compatible with (most) node API's.
• Do we migrate to Bun.env?

Learnings

• Compiling artisan with Bun doesn't seem to run, this is mainly due to the tmp package that is incompatible. module.exports gets aliased and Bun doesn't like that.
