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.

+## Профиль цивилизаций на шестой скорости

+godot --headless --path Owniverse.GI --script res://tests/benchmark_civilizations.gd -- frames=20 profile
+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.
