* useTrainingLayout Hook - Enhanced Responsive Training Layout
*
* Custom hook for managing responsive training 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 layout 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 layout constants to prevent cascading re-renders
* - Targets <1ms execution time for layout calculations
*
* @param width - Screen width
* @param height - Screen height
*
* @returns Layout constants and training area bounds
*
* @example
* ```typescript
* const { layoutConstants, trainingAreaBounds, isMobile, screenSize } = useTrainingLayout(1200, 800);
* ```
