Pull request overview

This pull request introduces a new coding standard rule SlevomatCodingStandard.Classes.ClassKeywordOrder that enforces the correct order of class modifiers in PHP. The rule ensures that when multiple modifiers are used on a class declaration (such as final, abstract, and readonly), they appear in the correct order: abstract or final must come before readonly.

Key changes:

• Adds ClassKeywordOrderSniff to detect and auto-fix incorrect modifier ordering
• Includes comprehensive test coverage with error and no-error test cases
• Updates documentation and project configuration to enable the new rule
