Missing DEVELOPMENT.md / CONTRIBUTING.md guides

[birkskyum]

It would be quite helpful to have some guides in this repo:

• DEVELOPMENT.md: Guidance on who to run the repo
• CONTRIBUTING.md: If contributions are welcome, and if so if there's something to be aware of like the @changesets/cli commit syntax, and who are currently active maintainers of the repo.

Before making modification, I want to see a green test pass. I attempt a build run, which returns me a message that there's no build scripts found:

➜ pnpm build

> vinxi-monorepo@ build /Users/admin/repos/vinxi
> pnpm -r --filter "./packages/*" run build

Scope: 13 of 43 workspace projects
None of the selected packages has a "build" script

Alright, so I go ahead with pnpm test, and it's just fails:

I'm not sure what's causing this.
