Pull Request Overview

This PR prevents duplicate checkstyle annotations in the PHPUnit workflow by refining warning detection and adding deduplication logic. It addresses cases where the same @covers warning could generate multiple annotations for the same file:line combination.

Key changes:

• Refines regex patterns for warning detection to improve accuracy
• Adds tracking of processed file:line combinations using an associative array
• Implements deduplication logic to skip already-processed annotations
