Pull Request Overview

This PR refactors the test running logic by moving run_tests to the module scope and reorganizing helper functions. Key changes include:

• Extracting helper functions (get_coro, wrap_in_sync, cancel_task) to module scope.
• Updating the _run_test_loop to return flaky tests for potential retries.
• Modifying the pytest_runtestloop hook to use the new test loop implementation.
