 * Overlay tracking for Escape key coordination.
 *
 * This solves the problem of escape key handling when overlays (like Select with onCancel)
 * are open. The CancelRequestHandler needs to know when an overlay is active so it doesn't
 * cancel requests when the user just wants to dismiss the overlay.
 *
 * Usage:
 * 1. Call useRegisterOverlay() in any overlay component to automatically register it
 * 2. Call useIsOverlayActive() to check if any overlay is currently active
 *
 * The hook automatically registers on mount and unregisters on unmount,
 * so no manual cleanup or state management is needed.
