- Rename D3D12Enum.h to D3D12Enums.h for naming consistency - Fix OpenGL unit test GLAD initialization by using gladLoadGL() instead of gladLoadGLLoader(wglGetProcAddress) for fallback support - Migrate remaining tests to use gtest_discover_tests for granular test discovery (math, core, containers, memory, threading, debug, components, scene, resources, input, opengl) - Remove obsolete TEST_RESOURCES_DIR and copy_directory commands from OpenGL unit test CMakeLists (minimal/Res doesn't exist) - Update TEST_SPEC.md with performance metrics and per-module build/test commands for faster development workflow - Update CMake path references to use lowercase paths

Mutex::lock
void lock() const;
获取互斥锁（const 版本）。如果锁已被其他线程持有，则阻塞当前线程直到锁可用。
该方法是 std::lockable 接口的实现，可与 std::lock_guard、std::unique_lock 等 RAII 工具配合使用。
参数： 无
返回： 无
线程安全： ✅
复杂度： 平均 O(1)，最坏情况 O(n)，n 为竞争线程数
示例：
#include "XCEngine/Threading/Mutex.h"
#include <mutex>
XCEngine::XCEngine::Threading::Mutex mtx;
int counter = 0;
void Increment() {
mtx.lock();
++counter;
mtx.unlock();
}
// 使用 RAII 自动管理锁
void SafeIncrement() {
std::lock_guard<XCEngine::Threading::Mutex> guard(mtx);
++counter;
}
