feat: 实现 GPU 加速管理功能
- 实现 enableGPU() 方法设置 will-change 属性 - 实现 disableGPU() 方法移除 will-change 属性 - 实现动画数量限制逻辑（最多 3 个同时运行） - 实现动画队列自动管理 - 添加 startAnimation() 和 endAnimation() 方法 - 添加 getActiveAnimationCount() 和 getQueuedAnimationCount() 查询方法 - 添加 clearAllAnimations() 清理方法 - 添加错误处理机制 - 创建交互式测试页面和自动化测试 - 创建详细的使用文档 验证需求： - 需求 5.2: 动画时使用 will-change 提示浏览器创建合成层 - 需求 5.3: 动画完成时移除 will-change 属性释放资源 - 需求 5.5: 限制同时运行的动画数量不超过 3 个
