Pull Request Overview

This PR switches the logging framework from Java util logging to SLF4J by updating imports, annotations, and log statements across the codebase. It replaces Lombok's @Log annotation with @Slf4j and migrates Java util logging syntax to SLF4J's parameterized logging format for better performance and clarity.

• Replace Lombok @Log with @Slf4j annotations across all Java files
• Convert Java util logging method calls to SLF4J syntax with parameterized messages
• Remove Java util logging imports and related configuration code
