> (aggressive) MIUI power management (https://dontkillmyapp.com/xiaomi)

### Proposed description

> Battery and Performance
> (aggressive) MIUI power management (https://dontkillmyapp.com/xiaomi)
> That's a weird app that also contains a DRM Manager and a service related to Cloud Backup
> Has obviously a lot of dangerous permissions.
> Removing this package can and (probably will) cause bootloop. Safe to disable.

I had hidden this package using AppDash(most likely it ran the command `pm hide`) once before, it caused the phone to bootloop after rebooting it. I had to factory reset it afterwards. Just disabling is safe.

Find the documentation file for the package 'com.miui.powerkeeper' in the project's data or documentation directory. Update the description to warn about bootloop risk when hiding the package, and clarify that disabling is safe. Verify the change by checking the file's format and running any documentation tests if present.
