Add benchmark for saved state performance

- Introduced `benchmark_saved_state.gd` to evaluate the performance of the saved state restoration process.
- Implemented JSON integer restoration to handle large integers accurately.
- Added command-line argument parsing for specifying the path to the diagnostic JSON file and optional delta seconds.
- Conducted performance tests at different speeds and logged the elapsed time for six consecutive steps.
- Created a new UID file for the benchmark script.

+Читает диагностический JSON формата 3 в отдельные экземпляры мира и замеряет
+шесть последовательных шагов на скоростях 1, 4, 6. Запись сохранений не вызывается.
+Последним аргументом можно задать длительность шага в реальных секундах
+(по умолчанию 1/60). Это время расчёта симуляции, без отрисовки интерфейса.
+
+При проверке регрессии на копии сохранения с 120 партиями шаг на скорости 6
+занимал около 1,3 секунды. Главная причина — перебор пустых завершённых окон
+коротких взрывов; дополнительная — повторное сокращение уже сокращённых дробей.
+После пропуска таких окон и устранения повторных НОД замеры составили 90–99 мс
+на шаг 1/60 секунды. Это ускорение примерно в 14 раз, но ещё не бюджет 60 FPS.
+Размер партии, точность чисел и правила эволюции не изменены. Разреженные
+сценарии дополнительно сравниваются с полным расчётом в `test_short_lived_events.gd`.
