laravel/reverb — reverse-engineered prompt

Build me a Laravel package that adds real time WebSocket support to a Laravel app. I want something that feels native to Laravel, so an app can send updates instantly to connected clients instead of polling all the time. The main goal is a backend service for real time communication, with a clean setup, sensible configuration, and a simple way for Laravel apps to publish events and have clients receive them.

Please include the pieces needed to actually run it, not just a demo, plus basic tests and enough docs or example usage that someone can install it and get a simple real time feature working quickly. Keep the developer experience straightforward, with config that can be customized when needed but works out of the box for common cases.

If there are Laravel conventions or current docs I should follow, look them up online and match those.
