## Overview

This change sets up "simple" `require-` type rules with the ability to
provide fixers, and configures `require-type` with a fixer that will add
`type: "commonjs"` if missing.

Per [Node.js docs](https://nodejs.org/api/packages.html#type), projects
without a "type" property default to CommonJS. Since adding "type":
"commonjs" simply makes this implicit default explicit without changing
runtime behavior, it is a safe, non-breaking autofix.
