ssdfasd 0f0ab8922a docs: fix naming conventions across threading, math, memory, core, and debug modules

threading/:
- Rename 19 camelCase method files to hyphenated names
- task-system: createtaskgroup→create-task-group, etc.
- tasksystemconfig: enabletaskprofiling→enable-task-profiling, etc.
- thread: getcurrentid→get-current-id, etc.
- task: addref→add-ref, getid→get-id, etc.

math/:
- Rename underscore operator files to hyphenated
- vector3: operator_add→operator-add, etc.
- matrix4: gettranslation→get-translation, etc.
- vector4: tovector3→to-vector3, constructor_vector3→constructor-vector3
- sphere: sphere_constructor→sphere-constructor, etc.

memory/:
- Remove duplicate memorymanager/ folder (kept manager/ which was correct)

core/:
- filewriter: Consolidate ctor-default.md and ctor-file.md into constructor.md
- Rename dtor.md→destructor.md

debug/:
- filelogsink: Rename construct.md→constructor.md, ~filelogsink.md→destructor.md

All overview pages updated with new file references.

Matrix4x4::GetRotation

Quaternion GetRotation() const

从变换矩阵中提取旋转分量。将矩阵转换为对应的四元数表示。

参数： （无）

返回： 旋转四元数

线程安全： ✅

复杂度： O(1)

示例：

#include "XCEngine/Math/Matrix4.h"
#include "XCEngine/Math/Quaternion.h"

using namespace XCEngine::Math;

Quaternion expected = Quaternion::FromEuler(0.0f, 90.0f, 0.0f);
Matrix4 transform = Matrix4::TRS(
    Vector3(0.0f, 0.0f, 0.0f),
    expected,
    Vector3(1.0f, 1.0f, 1.0f)
);

Quaternion rotation = transform.GetRotation();
// rotation 表示相同的旋转
