Standardize @Retention usage in Lombok annotationsfix: Standardize @Retention usage in annotations

[xpmxf4]

Description

This pull request standardizes the usage of the @retention annotation across Lombok's annotations. Specifically, it changes the usage in the @builder annotation from @Retention(SOURCE) to @Retention(RetentionPolicy.SOURCE).

Reason for Change

The other annotations in the Lombok project, such as @getter and @Setter, use @Retention(RetentionPolicy.SOURCE). For the sake of consistency and readability, this change ensures that all annotations follow the same convention.

Changes Made

• Updated @Retention(SOURCE) to @Retention(RetentionPolicy.SOURCE) in the @builder annotation.

Impact

This change does not affect the functionality of the annotations but improves the consistency and maintainability of the codebase.

Verification

No additional tests are needed as this change only affects the annotation declaration style.

Please review and let me know if there are any concerns or further changes needed.

Thank you!

There's a @Target annotation immediately above that also isn't consistent.

This isn't a meaningful update unless:

• You go the other way - Builder is right ,Setter is wrong: You want the static imports and the @RetentionPolicy(SOURCE), you've moved us to a more consistent, but less desired place. The PR should update Getter, Setter etc instead.
• It needs to cover all the annotations. So, also @Target, which also needs to move to a 'use star-static imports' mode.

NB: Stylistically it's star imports, because annotations predetermine what the values can be; The RetentionPolicy. adds nothing useful.
