Taking control of toolbar items in SwiftUI

SwiftUI adds finer toolbar control: set visibilityPriority (.automatic/.low/.high) on ToolbarContent to influence which items collapse; group actions with ToolbarOverflowMenu (always-collapsed); pin key buttons via .topBarPinnedTrailing; and use toolbarMinimizeBehavior to minimize nav/tab/bottom/window bars on scroll.

AsyncImage improvements in iOS 27
