Give only the macOS matrix leg two retries so actor/PTY timing
flakes do not strand otherwise-green runs. Linux and Windows remain

Deats,
- add the pytest-dev-maintained plugin to testing deps
- keep a one-second delay between macOS attempts
- validate the workflow, lock and both observed flaky test areas
