is-a-dev/register ? reverse-engineered prompt

Build me a community run service like is a dev where developers can claim a free, nice looking subdomain for their personal website, using something like name.is a dev. I want the whole flow to feel simple, people should be able to fork the project, add their requested domain details, open a pull request, and have automatic checks catch invalid or spammy submissions before a maintainer reviews it. Once a request is approved, the DNS records should go live pretty quickly through Cloudflare.

Please include the core registration logic, validation tests, clear contributor instructions, terms of service, security and code of conduct pages, and an abuse reporting path for bad domains or policy violations. It should feel like an open source repo that a small volunteer team could actually run, not a big corporate product. A simple README that explains how to request a subdomain and what happens after approval would be great too. Look up current Cloudflare and GitHub docs if you need to.
