Grant, deny, or reset an app's runtime permissions (camera, microphone, photos, contacts, notifications, calendar, location, location-always, media-library, motion, reminders) on an iOS simulator or Android device using the argent `settings-permissions` tool - without navigating the system Settings UI. Use when the permission cannot be changed through the app itself - and only then, pre-authorize before the app asks, deny up front, re-enable a permission the user already denied, or reset so the prompt reappears. If the app can flip it - via an in-app toggle or the system permission dialog the app triggers - interact with the app instead.
