fix(ci): resolve mypy type-ignore codes and windowed-EXE stdout crash

- Wrap sys.stdout.write() in try/except for PyInstaller --windowed builds
  where stdout is None (AttributeError crash on --version flag)
- Simplify smoke test to exit-code-only check (windowed EXE has no stdout)
- Remove unused type: ignore[override] from drop_zone and option_card
  (N802 is now globally suppressed in ruff; mypy no longer raises override)
- Change type: ignore[union-attr] → type: ignore[attr-defined] in
  step_processing and step_done (correct mypy error code)
- Add type: ignore[attr-defined] to theme.py QCoreApplication calls
