Add configuration options to support file refresh/reopen

When using this project as an idea plugin, the modified file import can not be displayed immediately like the idea format. I need to click on another file and go back to the currently modified file, to display the modified result.

Is there a way to update like format code in real time by calling idea's interface?

The issue identifies the IDEA plugin integration but names no files, tests, or entry points. Start by locating the plugin's file refresh or reopen handling, then determine how to verify that modified imports appear immediately without switching files.
