Add Lombok utility class migration recipe

[Ouweshs28]

What's changed?

• Added UseLombokUtilityClass to convert conservative static-only utility classes to Lombok @UtilityClass.
• Registered the recipe in LombokBestPractices and updated recipes.csv.
• Added safety checks for constructors, instance members, inheritance, instantiation, constructor method references, non-star static imports, nested-class legality, Lombok configuration, and annotation-name collisions.
• Added positive and negative recipe coverage.

What's your motivation?

• Closes Auto Lombok @UtilityClass #512.

Anything in particular you'd like reviewers to focus on?

The candidate safety criteria and the lombok.config resolution logic. The recipe intentionally skips uncertain cases, including non-star static imports and unresolved imported config files.

Anyone you would like to review specifically?

N/A

Have you considered any alternatives or workarounds?

• This follows the prior work in openrewrite/rewrite#3306, but reimplements it in this module with the safety concerns raised in that review addressed.

Any additional context
