extends Node
## Игровой контроллер без UI: связывает Game, HourDirector, Shop и SaveManager
## в законченный цикл «меню → подготовка → час → итоги часа → итоги забега».
##
## Контроллер не знает о сценах и не создаёт UI. Он тикает HourDirector вручную
## (UI вызывает tick(delta) из своего _process) и отдаёт готовые снимки данных
## через prep_data()/hour_data(). Фазы контроллера:
##   menu → prep → hour → hour_result → prep … → run_result
##
## Важно: Game.end_hour() вызывается только в next_after_hour(), чтобы UI успел
## показать отчёт часа. Если Game завершил забег сам (9-й час или SLA = 0),
## сигнал Game.run_ended переводит контроллер в run_result без дублирования.
