- Defer instantiation of heavy services (SyncService, UserService, ImportExportService, SystemService, ExecutionService) using cached properties in ServiceProvider and module __getattr__ in services. - Defer Google Drive SDK imports in sync_service.py using module-level __getattr__ and _get_google_libs() helper while retaining mock patchability. - Lazy load inquirer, Forms, Validators and Blessed theme adapters in connpy/cli/* to prevent loading CLI form dependencies at startup. - Clean up unused top-level service imports in connapp.py.
