refactor: remove lombok and replace all annotations with plain java implementations (#377)
* refactor: remove Lombok and replace with explicit Java code This change removes all Lombok annotations from the codebase and manually implements the equivalent constructors, builders, getters, equals/hashCode, and toString methods where required. The goal is to eliminate the Lombok dependency, improve Java version compatibility, and make the generated behavior explicit and maintainable. No functional changes were made.
