/**
 * @file Auto-Prioritized Hydration System
 * @description World-class hydration system for React applications.
 *
 * This module provides a complete solution for optimizing React hydration:
 *
 * ## Key Features
 *
 * - **Priority Queue System**: 5 levels (critical, high, normal, low, idle)
 * - **Visibility-Based Hydration**: Using IntersectionObserver
 * - **Interaction-Triggered Hydration**: Immediate hydration on user input
 * - **Idle-Time Background Hydration**: Using requestIdleCallback
 * - **Hydration Budget Management**: Never blocks main thread
 * - **Interaction Replay**: Captures and replays events during hydration
 * - **Progressive Hydration**: Partial hydration support
 * - **Performance Metrics**: Comprehensive telemetry
 *
 * ## Performance Targets
 *
 * - INP (Interaction to Next Paint): < 100ms
 * - TTI (Time to Interactive) reduction: 40%
 * - Zero main thread blocking during hydration
 *
 * ## Quick Start
 *
 * @example
 * ```tsx
 * // 1. Wrap your app with HydrationProvider
 * import { HydrationProvider } from '@/lib/hydration';
 *
 * function App() {
 *   return (
 *     <HydrationProvider config={{ debug: true }}>
 *       <YourApp />
 *     </HydrationProvider>
 *   );
 * }
 *
 * // 2. Wrap components with HydrationBoundary
 * import { HydrationBoundary } from '@/lib/hydration';
 *
 * function HeroSection() {
 *   return (
 *     <HydrationBoundary priority="critical" trigger="immediate" aboveTheFold>
 *       <ExpensiveHeroContent />
 *     </HydrationBoundary>
 *   );
 * }
 *
 * // 3. Use hooks to monitor and control hydration
 * import { useHydrationMetrics, useHydrationStatus } from '@/lib/hydration';
 *
 * function Dashboard() {
 *   const metrics = useHydrationMetrics();
 *   const heroStatus = useHydrationStatus('hero-section');
 *
 *   return (
 *     <div>
 *       <p>Progress: {metrics.hydrationProgress.toFixed(0)}%</p>
 *       <p>Hero status: {heroStatus.state}</p>
 *     </div>
 *   );
 * }
 * ```
 *
 * ## Architecture
 *
 * ```
 * HydrationProvider
 *     |
 *     +-- HydrationScheduler (singleton)
 *     |       |
 *     |       +-- PriorityQueue
 *     |       +-- IntersectionObserver
 *     |       +-- InteractionReplayManager
 *     |
 *     +-- HydrationBoundary (multiple)
 *             |
 *             +-- Status tracking
 *             +-- Placeholder rendering
 *             +-- Event capture
 * ```
