apache/couchdb — reverse-engineered prompt

Build me a working local CouchDB setup from this repo that I can actually run and try out on my machine. I want it to behave like a reliable document database with an HTTP and JSON API, plus the built in web admin interface so I can poke around in the browser.

Please make the developer setup as smooth as possible so I can start the server, or even a small local multi node cluster, without a lot of manual steps. I’d like to be able to launch it, optionally set an admin username and password, open it on port 5984, and use the browser verify install page to confirm everything is working. If it makes sense, set it up so I can also test syncing or replication between nodes locally.

Add any small scripts or notes needed so I know how to start it, stop it, and run the basic test suite. If anything is unclear, look up the current CouchDB install and developer docs online and use the recommended approach.
