- Create AutoModeServiceCompat as compatibility layer for routes
- Create GlobalAutoModeService for cross-project operations
- Update all routes to use AutoModeServiceCompat type
- Add SharedServices interface for state sharing across facades
- Add getActiveProjects/getActiveWorktrees to AutoLoopCoordinator
- Delete obsolete monolith test files
