Matrix4x4::operator*
Matrix4x4 operator*(const Matrix4x4& other) const
Vector4 operator*(const Vector4& v) const
两个重载分别用于矩阵与矩阵乘法，以及矩阵与四维向量的乘法。
参数（矩阵乘法）：
other- 右侧矩阵
参数（向量乘法）：
v- 四维向量
返回：
- 矩阵乘法：结果矩阵
- 向量乘法：变换后的四维向量
线程安全： ✅
复杂度： O(n²) - 矩阵乘法为 O(4³)，向量乘法为 O(4)
示例：
#include "XCEngine/Core/Math/Matrix4.h"
#include "XCEngine/Core/Math/Vector4.h"
using namespace XCEngine::Math;
Matrix4 m1 = Matrix4::RotationY(1.0f);
Matrix4 m2 = Matrix4::Translation(Vector3(1.0f, 0.0f, 0.0f));
Matrix4 combined = m1 * m2;
Vector4 v(1.0f, 0.0f, 0.0f, 1.0f);
Vector4 transformed = m1 * v;
