August 2025 monthly summary for apache/fesod: Delivered two major robustness enhancements with full test coverage. Implemented setIfNotNull in StyleUtil to apply setters only when values are non-null, reducing NPE paths; added comprehensive unit tests for StyleUtil. Refactored FastExcelFactory to use null-safe builders and reduced duplication, with accompanying unit tests for factory methods. These changes boosted reliability for style application and Excel export, decreased risk from null inputs, and improved maintainability. Committed changes: 2bf3402bc78c8ce0a1e82a6176599902a9a2379e (StyleUtil refactor: optimize the StyleUtil code (#466)); 97f4e8a6649af4f8024f44462ffbf1c5ff9d9b20 (refactor: FastExcelFactory (#454)). Business value: fewer null-related defects, faster feature delivery due to safer refactors, stronger CI confidence.
