[Improvement] add gradle window script and update spotless check stage

### What would you like to be improved?

Hi team, I find the project is missing `gradlew.bat` script, I suggest add this script for the use who dev on windows.

Another thing I noticed is we use `spotless` to format our code, but it will run before `compileJava` stage.
So when I change code and run unit test, I need run format command before test.
```
tasks.named("compileJava").configure {
dependsOn("spotlessCheck")
}
```
How about we
- change this format check after `test`
- add a CI to check code style
- give a `pre-commit` script, user can put it into git hook folder, then before each commit it will auto run `spotlessApply` command

### How should we improve?

_No response_

Start by locating the Gradle build configuration and current Spotless task wiring, then inspect how repository scripts and CI checks are organized. Review the requested gradlew.bat, post-test formatting check, CI style check, and pre-commit options with maintainers; the work is done only when the agreed subset is implemented and its relevant checks pass.
