refactor: migrate monorepo to bun v1.3.x

[alanrsoares]

Summary

Migrates the entire monorepo from pnpm + Node to Bun v1.3.x.

This includes:

• Updating all GitHub Actions workflows to use oven-sh/setup-bun and replace pnpm commands with bun equivalents.
• Switching test, build, and migration scripts to bun run.
• Updating local dev tooling (Tiltfile, Husky, lint-staged) to use Bun.

Didn't we want to use bun and pnpm?

We could, but it wouldn't have any benefit since we already have the bun toolchain.

The most noticeable things that has changed for my eyes was the dist dir replaced by src. What is the matter there?

Tried to run bun test in packages/api-main/ and tests failed:

SyntaxError: Export named 'assert' not found in module 'bun:test'.

bun test uses the bun native test runner, our test suit is built with vitest, so you need to use bun run test to actually hit the correct npm script in package.json

Using bun as the runtime, code collocation in the monorepo doesn't require any build step, so the modules can be server from the ts source directly.

Does this work natively with Netlify? At the moment it expects dist as the directory. It is defined in the settings.

We still build the frontend since it runs on the client, it can't be raw typescript. Everything else that runs on the server can be typescript native.
