- Replace ignore_errors: true with failed_when: false in 5 files
(main.yml, users.yml, ubuntu.yml, umount.yml, test-wireguard-real-async.yml)
- Add pytest.ini configuration for test discovery
- Add tests/conftest.py with shared fixtures and mock helpers
The failed_when: false pattern is preferred by ansible-lint as it
explicitly indicates expected failure handling rather than silently
ignoring all errors.
