enmity-mod/enmity ? reverse-engineered prompt

Build me an Enmity style Discord companion app that gives people a simple way to use plugins and themes, and exposes some of Discord’s built in internal functionality for addons to hook into.

I want it to feel like a polished modded Discord experience, with a clean interface for browsing, enabling, disabling, and managing addons, plus support for customizing the look with themes. Make it easy for users to install and update things without having to understand the internals.

Please also include the pieces needed for developers to build addons against it, with sensible docs or examples so it’s clear how to extend the app. If you need to check current docs or best practices online, feel free to do that.
