Description

在多线程场景下，光凭线程ID很难知道具体是哪里的线程。java中创建线程或线程池时，都可以指定名称，这样就很容易知道是哪个线程执行了该方法，有线程名称输出似乎更加容易定位问题，但光凭线程ID很难判断。

是否可以在native logWrite2方法增加线程名称输出？

Research direction
Locate the native logWrite2 method in the mars codebase (likely in the C++ source files). Research how to retrieve the current thread name in a cross platform manner (e.g., pthread getname np on Linux/macOS, GetThreadDescription on Windows). Implement a function to fetch the thread name and add it to the log output alongside the thread ID. Ensure it works on all platforms mars supports. Consider performance implications of calling the thread name function on every log write.
