Add phone-workout GitHub sync via shared crdt_sync (Workstream C)
Sync the workout log across devices using the shared crdt-sync /
crdt_sync_dart CRDT transport (same scheme as diet_guard).

- Python: new _workout_sync.py + _temperature_status_mixin.py; wire sync
  into screen_lock.py / status_view.py; add the crdt-sync git dependency
  and test_sync_fixtures / test_workout_sync suites.
- Dart (workout_app): new workout_sync_service.dart, github_device_auth.dart,
  sync_settings.dart with tests + fakes; settings/workout screens updated.
- docs: workstream-d-shared-crdt-transport.md.

Verification: pytest 747 passed at 100% coverage; flutter analyze clean;
flutter test passed.

"""Live Warsaw-temperature background check mixin for ``StatusWindow``.
Fetches the same reading the real locker's heat-skip check would see
(``_temperature.fetch_current_temp_with_status``), in a background thread,
bounded to ``_temperature.HARD_TIMEOUT_SECONDS`` — display-only, never
writes to ``workout_log.json``. Host class must provide:
- ``self.root`` — the Tk root, for ``root.after`` polling.
- ``self.temperature_fetcher`` — injected fetch callable (tests override it).
- ``self._temp_future`` / ``self._temp_result`` — state slots, initialized
by the host's ``__init__``.
- ``self._last_snapshot`` — the most recently rendered ``StatusSnapshot``.
- ``self.render(snapshot)`` — full redraw, called after a result resolves.
