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

# Mesh::SetVertexData
```cpp
void SetVertexData(const void* data, size_t size, Core::uint32 vertexCount,
Core::uint32 vertexStride, VertexAttribute attributes)
```
设置网格顶点数据。复制顶点缓冲数据到内部存储。
**参数:**
- `data` - 顶点数据指针
- `size` - 数据大小(字节)
- `vertexCount` - 顶点数量
- `vertexStride` - 单个顶点结构体大小(字节)
- `attributes` - 顶点属性标志组合
**返回:**
**复杂度:** O(n)n 为顶点数据大小
**示例:**
```cpp
struct Vertex {
float position[3];
float normal[3];
float uv[2];
};
mesh->SetVertexData(vertices.Data(), vertices.Size() * sizeof(Vertex),
vertexCount, sizeof(Vertex),
VertexAttribute::Position | VertexAttribute::Normal | VertexAttribute::UV0);
```
