ssdfasd dc850d7739 docs: 重构 API 文档结构并修正源码准确性
- 重组文档目录结构: 每个模块的概述页移动到模块子目录
- 重命名 index.md 为 main.md
- 修正所有模块文档中的错误:
  - math: FromEuler→FromEulerAngles, TransformDirection 包含缩放, Box 是 OBB, Color::ToRGBA 格式
  - containers: 新增 operator==/!= 文档, 补充 std::hash DJB 算法细节
  - core: 修复 types 链接错误
  - debug: LogLevelToString 返回大写, timestamp 是秒, Profiler 空实现标注, Windows API vs ANSI
  - memory: 修复头文件路径, malloc vs operator new, 新增方法文档
  - resources: 修复 Shader/Texture 链接错误
  - threading: TaskSystem::Wait 空实现标注, ReadWriteLock 重入描述, LambdaTask 链接
- 验证: fix_links.py 确认 0 个断裂引用

# IResourceLoader::LoadAsync
```cpp
void LoadAsync(const Containers::String& path, const ImportSettings* settings,
std::function<void(LoadResult)> callback)
```
异步加载资源。默认实现直接调用同步 `Load` 方法并在当前线程执行回调。子类可重写以实现真正的多线程异步加载。
**参数:**
- `path` - 资源路径
- `settings` - 导入设置(可为 nullptr
- `callback` - 加载完成回调函数
**返回:**
**复杂度:** O(n)
**示例:**
```cpp
void AsyncTextureLoader::LoadAsync(const Containers::String& path,
const ImportSettings* settings,
std::function<void(LoadResult)> callback) {
std::thread([this, path, settings, callback]() {
LoadResult result = Load(path, settings);
callback(result); // 回调可在工作线程执行
}).detach();
}
```
