研究方向

Start by reviewing the reference PR #23273 which added a similar plugin for TypeScript generators. Look at the Scala generator classes in the codebase, such as `ScalaClientCodegen` and `ScalaServerCodegen`, to understand how existing plugins are configured. Also check the build configuration (e.g., `build.gradle`) to see how dependencies and tasks are added. The issue requires adding scalafmt as a plugin that runs formatting on generated Scala code, similar to how the TypeScript counterpart is done.
