fix(tests): enhance Windows compatibility and test stability

- Normalize file paths to use forward slashes in Git pattern matching for better compatibility across platforms.
- Introduce a random suffix to temporary directory names in tests on Windows to avoid file lock contention during parallel execution.
- Add a delay after shutdown in tests to ensure SQLite file locks are released properly on Windows.

These changes aim to improve the reliability and consistency of tests in a Windows environment.
