/**
 * useCombatLayout Hook - Enhanced Responsive Combat Layout
 *
 * Custom hook for managing responsive combat screen layout calculations with
 * comprehensive support for all screen sizes from mobile to ultra-wide displays.
 *
 * Enhanced Features:
 * - Five screen size categories (mobile, tablet, desktop, large, xlarge)
 * - Proportional scaling for consistent sizing across devices
 * - Optimized arena sizing for each device category
 * - Smooth transitions for resize operations
 * - 60fps performance maintained
 *
 * Uses robust device detection combining user-agent and screen size to ensure
 * mobile controls are shown on all mobile devices, including high-resolution phones.
 *
 * Performance:
 * - Reduces recalculations by checking only breakpoint changes, not exact dimensions
 * - Memoizes arena bounds to prevent cascading re-renders
 * - Targets <1ms execution time for layout calculations
 *
 * @param width - Screen width
 * @param height - Screen height
 *
 * @returns Layout constants and arena bounds
 *
 * @example
 * ```typescript
 * const { layoutConstants, arenaBounds, isMobile, screenSize } = useCombatLayout(1200, 800);
 * ```
