prevent redundant test execution

fixes #33

[Copilot]

Pull request overview

This PR fixes issue #33 by preventing redundant test execution when both module-level (pytestmark) and function-level (@pytest.mark.isolated) markers are applied to the same test. The fix introduces logic to detect function-level markers and prioritize them over inherited module/class markers for test grouping.

Changes:

• Added marker precedence logic to prevent duplicate test runs when overlapping markers are present
• Added comprehensive tests to verify correct behavior with overlapping markers and proper failure reporting
• Bumped version to 0.4.4 to reflect the bug fix
