 This release focuses on project robustness and delivery quality. It adds a comprehensive suite of unit and case-based tests, plus CI workflows to run PHPUnit and PHPStan. It also includes extensive documentation and an automated release pipeline that produces artifacts (source ZIP and documentation PDF) with versioned release notes. The engine received a small tag/dialect handling refactor to enable future improvements without impacting expected performance.
