Pull request overview

This PR implements smart change tracking for the CI/CD pipeline to optimize test execution by only running tests for modules that have changed. The workflow now detects which module groups have been modified and conditionally executes corresponding test suites.

Changes:

• Added change detection using path filters to identify modified module groups
• Refactored test execution to batch all Gradle tasks and run them in a single command
• Added conditional execution logic to skip test jobs when their modules haven't changed
• Configured concurrency control to cancel in-progress runs when new commits are pushed
