Add new tests and implement frame budget management

- Introduced `civilization_benchmark.gd` and `legacy_quantity_math.gd` for benchmarking and legacy quantity calculations.
- Created `test_dynamic_math.gd`, `test_frame_evolution.gd`, and `test_sparse_batches.gd` to validate mathematical operations and frame evolution logic.
- Implemented `frame_budget.gd` to manage cooperative work on the main thread, ensuring no partially calculated state is published.
- Added UID files for all new scripts to maintain unique identifiers.

 Проверяются реальные коэффициенты C0.2, войны и побочный ущерб C2.0, замена планет колониями с сохранением хозяина, дипломатическое влияние, бонус периода от структур и деградация при их отсутствии. Ускоренная модель проходит все стадии C0.2 → C4.4 → Ct. Проверки контролируют сохранение населения, целочисленность этик, валидацию сохранения и детерминированное продолжение после сериализации.

+godot --path Owniverse.GI --script res://tests/benchmark_civilizations.gd -- ui scenario=mixed frames=10 profile
+```
+
+Сценарии `mixed`, `large`, `fragmented` заполняют все стадии и этики, синхронизируя
+переходы; `large` использует по 6e20 цивилизаций, `fragmented` — десять партий.
+Это искусственные стрессовые сценарии. `scenario=stable` использует штатные
+сроки стадий. Параметр `snapshot=/tmp/civil` сохраняет состояние каждого сценария
+для сравнения до и после изменения. UI запускает настоящую сцену со страницей
+жизни и реальным delta, без загрузки и записи сохранения игрока.
+
+`profile` выводит суммарные микросекунды и число вызовов по этапам. Вложенные
+этапы входят во время родительских; складывать их нельзя. В игре сбор выключен.
+Кэши физических количеств принадлежат отдельному миру и проверяют изменения
+количеств, вложенных привязок и индексов каталога. Кэш структуры правил не входит
+в сохранение: при изменении Claim/бонусов нужно перестроить индексы каталога,
+при изменении home в существующей таблице — invalidate_civilization_layout().
+
+После оптимизации на M4 Pro, по 20 шагов 1/60 секунды, среднее время:
+`mixed` 295 → 235 мс, `large` 666 → 539 мс, `fragmented` 359 → 282 мс.
+Полные состояния всех трёх сценариев после 20 шагов совпали до и после изменения.
+Дополнительно тест распределений сравнивает новый путь с прежним на 300
+случайных наборах, включая 1e40 и накопленные долги округления.
+
+## Расчёт между кадрами
+
+`godot --headless --path Owniverse.GI --script res://tests/test_frame_evolution.gd`
+
+Stage вызывает `evolute_frame`: транзакция получает бюджет 40 мс и уступает
+следующему кадру внутри создания партий и обработки стадий. Расчёт остаётся
+на главном потоке, состояние публикуется только после полного завершения.
+Длительность одной транзакции ограничена обычным шагом 1/60 секунды выбранной
+скорости. Запрошенное время хранится отдельно, поэтому отставание не превращается
+в один всё более тяжёлый шаг. При предельной нагрузке время симуляции может
+отставать от запрошенного; это не ограничение FPS интерфейса и не удаление событий.
+
+Производство во время транзакции выполняется после её завершения. Запрошенное
+время, активный интервал, скорость и очередь производства входят в сохранение;
+при загрузке незавершённый интервал пересчитывается с опубликованного состояния.
+Сброс мира отменяет отложенный расчёт. Тест проверяет точное совпадение непрерывного
+и распределённого расчёта, очереди, переключение скорости, восстановление и отмену.
+
+На M4 Pro, 180 кадров реального UI на шестой скорости: смешанный сценарий
+15.9 FPS (максимальный кадр 98 мс), большие количества 17.5 FPS (106 мс),
+много партий 16.3 FPS (97 мс).
+Это FPS отрисовки, а не число завершённых транзакций симуляции в секунду.

 # Числа симуляции
 
-`exact.gd` сохраняет единый API `E` для симуляции и интерфейса. Целые числа,
-помещающиеся в `int64`, остаются обычными `int`. Остальные значения хранятся
-в `exact_value.gd`:
+Целые значения в диапазоне int64 хранятся как `int`. Остальные числа имеют вид
+`polarity × (sum(whole[i] × 10^(9i)) + fraction)`:
+`whole` — динамический массив целых блоков по основанию 10^9,
+`fraction` — float от 0 включительно до 1 исключительно. Числа после создания
+не изменяются. Ограничения E27 в хранении нет; размер массива растёт по необходимости.
 
-```
-polarity × (high × 10^14 + low + fraction)
-```
+Используйте API `E.add/subtract/multiply/divide`, `E.eq/lt/le/gt/ge` и
+`E.floor_value/ceil_value/round_value`. Обычные операторы над ExactValue не работают.
+`E.integer` требует значения в диапазоне int64; `E.approx` явно преобразует
+число в float и для очень больших чисел возвращает бесконечность.
+Сравнение через E сохраняет отличие конечного большого числа от INF.
 
-`high` и `low` — целые блоки от 0 до 10^14−1, `fraction` — `float` от 0 до 1,
-`polarity` — знак. Значения неизменяемы после создания. Диапазон включает весь
-порядок E27: модуль целой части меньше 10^28. Каждая единица целой части
-сохраняется, в том числе при добавлении и вычитании единицы около 10^27.
-Выход за диапазон проверяется утверждениями; насыщения или обрезания запасов нет.
+Целые операции выполняются точно. Умножение и деление используют безопасные
+разряды из `big_integer.gd`; нативная арифметика применяется при отсутствии
+переполнения int64. `E.mul_div(count, numerator, denominator)` сохраняет точное
+целое частное, не превращая заранее отношение в приближённый коэффициент.
+`E.floor_sum` суммирует округлённые линейные квоты без перебора каждого окна.
 
-Числители и знаменатели в состоянии больше не хранятся. НОД при обычных
-арифметических операциях не вычисляется; обход состояния для ограничения дробей
-больше не нужен. `bounded` и `bound_state` оставлены как совместимые пустые операции.
+Дробный остаток приблизительный: при умножении и делении он преобразуется
+в десятичную дробь с 16 значащими цифрами. При сложении двух ненулевых остатков
+перенос около целой границы стабилизируется с допуском 10^-12.
+Умножение большого количества на float усиливает ошибку коэффициента;
+для известных точных отношений используйте mul_div. Целые распределения
+и сохранение числа объектов проверяются строго, без допуска.
 
-## Операции
+Возраст сохраняет точную целую часть. Только дробная часть переводится в
+наносекундные тики, дополнительный остаток времени переносится между кадрами.
+Синхронный диагностический API evolute отклоняет шаги от 1e27 игровых лет:
+это защита от непрактичного интервала, а не предел хранимого возраста.
+Покадровый API ограничивает одну транзакцию обычным шагом 1/60 секунды;
+остальное запрошенное время остаётся в очереди.
 
-Сложение, вычитание и сравнение работают непосредственно с блоками.
-Деление int64 и объединённое умножение/деление при безопасном произведении
-используют нативную арифметику. Перевод больших целых между блоками и временными
-разрядами, извлечение коэффициента и сборка результата обходятся без строк.
-Дробный коэффициент нормализуется численно до 16 значащих цифр; последние биты
-float могут отличаться от результата прежнего строкового преобразования.
-Для умножения и деления `big_integer.gd` используется как временный вычислитель
-с безопасными разрядами по основанию 10^9. Результат сразу возвращается в
-фиксированную структуру. Размер временных дробей определяется входными float,
-а не растёт от шага к шагу.
+Формат сохранения — **5**, версия состояния — **0.3.0**.
+Большие целые и числа с дробью кодируются как
+`{"$exact": [[blocks], "float bytes in hex", sign]}`.
+Байты остатка сохраняются без потери точности JSON. Миграции старых форматов нет.
 
-`E.mul_div(a, b, denominator)` вычисляет отношение за одну операцию. Это нужно
-для распределений: произведение двух количеств может превышать E27, хотя итог
-деления укладывается в диапазон. Промежуточное произведение не становится
-значением симуляции. Целое частное вычисляется до перевода остатка в float.
-
-```gdscript
-const E = preload("res://world/owniverse/math/exact.gd")
-var stock = E.of("1e27") # Большое целое вводится строкой.
-stock = E.subtract(stock, 1)
-var share = E.mul_div(stock, 15, 100) # Точные 15% целого запаса.
-var whole_share = E.floor_value(share)
-```
-
-Использовать `E.add/subtract/multiply/divide`, `E.eq/lt/le/gt/ge`,
-`E.floor_value/ceil_value/round_value`. Обычные операторы над объектами
-`ExactValue` не подходят. `E.integer` допускается только для значений int64;
-`E.approx` — явный переход к приближённому float.
-
-## Дробная точность
-
-Дробная часть приближённая. Для временного умножения/деления она преобразуется
-в десятичную дробь с 16 значащими цифрами; нормализация сохраняет значащие цифры
-малых коэффициентов. Десятичные стоимости вроде 0.125 и 0.0000000000001
-сохраняют корректный размер производственной партии. НОД применяется только
-при определении знаменателя стоимости в `production_step`.
-
-При сложении двух ненулевых дробных частей перенос около целой границы
-стабилизируется с допуском 10^-12. Это предотвращает задержку редких событий
-из-за накопленной ошибки float. Допуск не применяется к целым блокам или
-округлению частного при делении. Суммы распределённых целых объектов проверяются
-строго, без допуска.
-
-При умножении большого количества на приближённый коэффициент ошибка самого
-коэффициента усиливается: float-доля не обещает точности результата до единицы.
-Известные точные отношения нужно передавать через `mul_div(count, numerator,
-denominator)`, не вычисляя коэффициент заранее.
-
-Возраст хранится как целые годы и дробный остаток; в наносекундные тики
-переводится только дробная часть года. Полный возраст больше не умножается на
-10^9. Остаток кадрового времени переносится отдельно. Геометрический объём
-пустот может превышать E27 из-за множителя 10^22: он вычисляется в float и
-используется только для приближённых коэффициентов плотности и бластов.
-
-Форматирование не создаёт больших промежуточных значений симуляции: например,
-округлённая подпись `1.00E+28` допустима для количества чуть меньше 10^28.
-
-## Сохранение
-
-Формат сохранения — **4**, версия состояния — **0.3.0**. Большие целые
-кодируются как `{"$exact": "целое число"}`. Блоки с дробью кодируются как
-`{"$fixed": ["high", "low", "float bytes in hex", sign]}`. Восемь байтов float
-сохраняются без потери точности JSON, включая очень малые остатки.
-Зашифрованный файл и диагностический JSON используют один снимок.
-
-Миграции нет. Сохранение прежнего формата при обычной загрузке архивируется
-существующим механизмом `.incompatible.bak`; начинается новая игра.
-Тесты не загружают и не перезаписывают рабочее сохранение игрока.
-
-## Проверки
-
-`godot --headless --path Owniverse.GI --script res://tests/test_exact_math.gd`
-
-Независимый эталон `tests/fixtures/exact_oracle.json` получен через Python
-`fractions.Fraction` (160 пар, seed 4321). Произведения находятся внутри E27;
-дробные результаты сравниваются с абсолютным допуском 10^-12, целые — точно.
-Дополнительно проверяются границы int64/E27, единичные изменения, точные
-проценты, объединённое умножение с делением, JSON, дробные рецепты,
-распределения, жизнь, энергия, время, форматирование и 100 циклов симуляции.
+Проверки: `test_exact_math.gd`, `test_dynamic_math.gd`, `test_quantity_catalog.gd`,
+`test_time.gd` и `test_frame_evolution.gd`. Независимый целочисленный эталон
+покрывает числа до 220 десятичных цифр; отдельные проверки — до E1000,
+границы int64, доли, сериализацию, распределения и продолжение расчёта.
