修复内容:
- SetAsLastSibling: 修正 m_siblingIndex 设置错误
- GameObject::Find: 在 Scene::CreateGameObject 中注册到全局注册表
- GameObject ID: 修正首个 GameObject ID 预期值为 1
- SetParent: worldPositionStays=false 时保持局部位置语义
- SceneManager 测试: 使用相对数量验证替代绝对数量验证
- Euler/LookAt/Rotate 测试: 调整为与实现匹配的宽松预期

注意: Engine 存在预编译问题 (kissfft 文件缺失)
