[Java Agent] 请问是否会考虑支持Agent的热更新

目前如果修改了Agent code，然后重新使用Attach方式注入，是不能升级成新版本的，这个有在文档中看到，不确定是否有技术可以实现热更新？

Start by reviewing the documentation describing Attach-based injection and the limitation when Agent code changes. Then investigate the Java Agent lifecycle and determine whether reattaching can replace the active version; done would require a clearly scoped feasibility conclusion or implementation plan.
