``android.autoinstalls.config.Xiaomi.model``

it works similar to android.autoinstalls.config.Xiaomi.cepheus, by installing apps on first setup, some phones use that instead of a codename. Like my redmi 9c which uses android.autoinstalls.config.Xiaomi.model.

Look at the existing Xiaomi device configurations in the codebase, likely in a file like `src/adb/devices.rs` or a similar module. The issue mentions adding `android.autoinstalls.config.Xiaomi.model` similar to the existing `cepheus` entry. Find where these package lists are defined and add the new model. Test by building and running the tool to see if the new entry appears in the GUI for the specified device.
