class MacOutsideClickWatcher(windowSupplier: () -> Window?, onOutsideClick: () -> Unit) : AutoCloseable
MacOutsideClickWatcher: encapsulates macOS-specific logic to detect a left-click outside the provided window and invoke a callback to hide it. It also ignores clicks on the macOS status bar tray icon (status item) so that clicking the tray icon does not spuriously hide the window.
