@aFlyBird0 Please check the ci error.

Sorry, new code has been committed. (I ran go test ... locally before committing. /... . But I forgot that I changed the code in the configloader via GitHub pilot, thinking it was a ci test like the last one.)

Very detailed change by @aFlyBird0. Thanks very much. I committed a few grammar updates in the PR directly; hope you won't mind.

Please do a regression test (for example, the GitOps process) to make sure the code change didn't break anything.

@aFlyBird0 keep up the good work!

[aFlyBird0]

Thanks for your additional commits sincerely! I will do the regression test this afternoon. @IronCore864

@aFlyBird0 @IronCore864 How about merge this pr now. I'll test it locally today. I'm also changing the logic of the package configloader, and this pr is actually in conflict with mine. I want to merge this pr to main and then merge it to my local branch, then I resolved the conflict and continued to develop, and then tested the related functions after I finished the development.
