Build me an Android library in Kotlin that lets an app set Discord Rich Presence from a phone. I want it to be easy to drop into another Android project, create a client with a Discord account token, and then send an activity with the usual Rich Presence fields like app id, name, details, state, activity type, start and end timestamps, image assets with hover text, button labels, button links, and user status like online, idle, or dnd.

Please also include a simple example Android app in the repo so I can test it quickly by entering sample values and sending an update. The library should feel clean and straightforward to use from Kotlin, with sensible data classes or models for activity, timestamps, assets, and metadata.

If anything is unclear, check current Discord Rich Presence behavior and Android docs online, then make the project build and run end to end with a clear README showing setup and a basic usage example.
