Fix #1240

[Copilot]

Pull request overview

This pull request adds test coverage for listener management in the WorkflowApplication, specifically testing the sorting by priority and deduplication of listeners. The PR introduces new test listener implementations and modifies WorkflowApplication to wrap the listeners collection in a LinkedHashSet to enable automatic deduplication while preserving insertion order from the priority-based sorting.

Changes:

• Add comprehensive test suite for WorkflowExecutionListener sorting and deduplication behavior
• Introduce test listener implementations with different priority levels to exercise the listener management logic
• Modify WorkflowApplication to use LinkedHashSet for listeners to ensure deduplication while maintaining priority-based order
• Add mockito-core test dependency for test infrastructure
