fun isMultiWindowConstrained(configuration: Configuration, ignoreMultiWindows: Boolean, context: Context? = null): Boolean
Returns true when the app is in a multi-window mode (split-screen, freeform, PiP) and the caller opted into suppressing scaling via ignoreMultiWindows.
Primary detection uses the public Activity.isInMultiWindowMode API (available since API 24, which matches the library's minSdk). When no Activity can be resolved from the supplied context, a heuristic based on Configuration dimensions is used as a best-effort fallback.
