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

# TaskGroup::WaitFor
```cpp
bool WaitFor(std::chrono::milliseconds timeout)
```
等待任务组中所有任务完成,可在超时后返回。
**参数:**
- `timeout` - 最大等待时间
**返回:** `bool` - 所有任务在超时前完成返回 true超时返回 false
**复杂度:** O(n)
**示例:**
```cpp
TaskGroup* group = TaskSystem::Get().CreateTaskGroup();
for (int i = 0; i < 5; ++i) {
group->AddTask([i]() {
Thread::Sleep(i * 100);
printf("Task %d done\n", i);
});
}
if (group->WaitFor(std::chrono::seconds(1))) {
printf("All tasks completed within 1 second\n");
} else {
printf("Timeout! Some tasks still running\n");
printf("Progress: %.1f%%\n", group->GetProgress() * 100.0f);
}
```
