/**
 * PreloadLink Component
 *
 * A Link component that preloads route modules on hover/focus for faster navigation.
 * Improves perceived performance by loading the next page before the user clicks.
 *
 * @example
 * ```tsx
 * // Basic usage with custom preload function
 * <PreloadLink
 *   to="/dashboard"
 *   preload={() => import('./pages/Dashboard')}
 * >
 *   Dashboard
 * </PreloadLink>
 * ```
 *
 * @example
 * ```tsx
 * // With route modules map
 * const routeModules = {
 *   '/': () => import('./pages/Home'),
 *   '/dashboard': () => import('./pages/Dashboard'),
 *   '/settings': () => import('./pages/Settings'),
 * };
 *
 * <PreloadLink
 *   to="/dashboard"
 *   routeModules={routeModules}
 *   languagePrefixes={['en', 'es', 'zh']}
 * >
 *   Dashboard
 * </PreloadLink>
 * ```
 *
 * @example
 * ```tsx
 * // With path normalizations for dynamic segments
 * <PreloadLink
 *   to="/dashboard/my-org/projects"
 *   routeModules={routeModules}
 *   pathNormalizations={[
 *     { pattern: /\/dashboard\/[^/]+/, replacement: '/dashboard' }
 *   ]}
 * >
 *   Projects
 * </PreloadLink>
 * ```
