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

# IAllocator::GetAllocationCount
```cpp
virtual size_t GetAllocationCount() const = 0;
```
返回当前处于已分配状态(未释放)的内存块数量。此方法用于监控活跃分配的数量。
**参数:**
**返回:** 当前已分配块的数量
**复杂度:** O(1)
**示例:**
```cpp
#include <XCEngine/Memory/IAllocator.h>
class MyAllocator : public IAllocator {
size_t m_count = 0;
public:
void* Allocate(size_t size, size_t alignment = 0) override {
++m_count;
return ::operator new(size);
}
void Free(void* ptr) override {
if (ptr) {
--m_count;
::operator delete(ptr);
}
}
void* Reallocate(void* ptr, size_t newSize) override { /* ... */ }
size_t GetTotalAllocated() const override { return 0; }
size_t GetTotalFreed() const override { return 0; }
size_t GetPeakAllocated() const override { return 0; }
size_t GetAllocationCount() const override { return m_count; }
const char* GetName() const override { return "MyAllocator"; }
};
MyAllocator alloc;
alloc.Allocate(64);
alloc.Allocate(128);
size_t count = alloc.GetAllocationCount(); // 返回 2
```
