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.

+# TaskSystemConfig::stealTasks
+
+```cpp
+bool stealTasks = true
+```
+
+是否启用工作窃取。当启用时，空闲的工作线程可以从其他繁忙线程的任务队列中窃取任务，提高整体吞吐率。
+
+**类型：** `bool`
+
+**默认值：** `true`
+
+**当前状态：** 此配置项当前未实际实现，工作窃取功能不可用。所有工作线程仅从全局任务队列获取任务。
+
+**示例：**
+
+```cpp
+TaskSystemConfig config;
+config.workerThreadCount = 8;
+config.stealTasks = true; // 预留配置项（当前未实现）
+```
