WHY IT NEEDS A POLICY

Why enable_screen_keep_alive needs a policy

This tool enables a screen keep-alive setting on the Android device, which is a reversible configuration change (its sibling tool 'disable_screen_keep_alive' reverses it). It modifies device state but does not delete data, execute arbitrary code, or involve financial transactions. Severity is low as misuse merely keeps the screen on, draining battery but causing no serious harm.
