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

# Vector3::MoveTowards
```cpp
static Vector3 MoveTowards(const Vector3& current, const Vector3& target, float maxDistance)
```
将当前向量朝目标向量移动指定距离。如果距离已小于 maxDistance则直接返回目标。
**参数:**
- `current` - 当前向量
- `target` - 目标向量
- `maxDistance` - 最大移动距离
**返回:** `Vector3` - 移动后的位置
**复杂度:** O(1)
**示例:**
```cpp
Vector3 current(0.0f, 0.0f, 0.0f);
Vector3 target(10.0f, 0.0f, 0.0f);
Vector3 moved = Vector3::MoveTowards(current, target, 3.0f); // (3.0f, 0, 0)
```
