/**
* Параметр `extensions` в RPC-запросе (`rpcClient.call`, тело: `method`, `params`, `extensions`, …)
* — это массив имён **связанных коллекций**, которые серверу нужно **догрузить** к основному ответу
* метода, не включая эти сущности в `result` целиком.
*
* **Зачем:** в схеме (см. `BaseType::extensionsStructure`) у полей-ссылок (`ID` / `IDs`) есть
* соответствующий документ в MongoDB. Без `extensions` в `result` остаются только идентификаторы;
* с `extensions` сервер (`ExtensionsResolver` в schema) по этим id выбирает документы из кэша/БД
* и возвращает их **отдельно** в поле `extensions` ответа: объект «имя коллекции → массив документов».
* Так клиент выбирает, какой граф данных подтягивать, и не платит за лишние join’ы.
*
* **Синтаксис строк:** `коллекция` — подгрузить на первом уровне от корневого результата;
* `a->b` и `a->b->c` — те же коллекции, но для **вложенных** уровней: сначала грузятся `a`, затем
* по id из полученных документов — `b`, затем `c` (см. `oneSubLevelExtensions` / `twoSubLevelExtensions`
* в `ExtensionsResolver`). Разрешённые значения для каждого метода задаются кодогеном из схемы.
*
* Перед `undefined` у конкретного вызова используется `rpcClient.setDefaultExtensions` (если задано).
* Пустой массив — дополнительные коллекции не запрашивать.
* 
* Далее в коде можно получить данные по примеру ExtensionStore.citiesByID(X) или ExtensionStore.citiesByIDs([X, Y, Z]) и т.д.
