Luminous418/cloudy-app ? reverse-engineered prompt

Build me an Android app that acts as an updater for the LumiROM series.

I want a simple app where users can check for new builds, see what version they are on, view the latest available update info, and download or open the update details from a JSON feed like the sample file in the repo. Keep the experience clean and easy to use, since this is meant for regular phone users, not power users.

If it makes sense, also support the Magisk module part that is already in the project so the updater can work alongside rooted devices. Make the main screen feel polished, with clear status, update availability, and a straightforward way to refresh.

Use the current project setup and look up any Android or Gradle details online if you need to. Please wire everything up so the app builds and runs nicely, and make sure the sample update data can be used to test the flow end to end.
