Delete old flat files, wire new DI in main.dart:
- Removed: gps_service.dart, config/, models/, providers/overlay_provider.dart,
screens/, services/gps_data_manager.dart, services/overlay_service.dart
- Kept: settings_provider.dart (thin, correct), logger.dart (shared util)
- main.dart now wires: LocationRepository → SpeedometerViewModel → SpeedometerView
- overlay_provider.dart deferred, stub in ui/features/overlay/
- flutter analyze: 30 info-level constant_identifier_names warnings (project convention),
zero errors, zero warnings — builds clean
New structure:
lib/
core/constants/ — gps, overlay, timing, speed_unit
core/theme/ — color_themes
data/
models/ — LocationData (immutable domain model)
services/ — GpsService (stateless wrapper), OverlayService (IPC)
repositories/ — LocationRepository (business logic, ChangeNotifier)
providers/ — SettingsProvider (thin, unchanged)
ui/
features/
speedometer/ — SpeedometerViewModel + SpeedometerView
overlay/ — Stub ViewModel + View (deferred)
shared/ — SpeedDisplay widget
services/ — Logger (shared util)
