Контекстные меню текстовых полей показывали «Cut / Copy / Cancel / Select all»: эти строки приходят из самой библиотеки, а переводчик к ней подключён не был. Библиотека везёт готовый qfluentwidgets.ru_RU.qm — теперь он ставится при запуске и переставляется при смене языка в настройках оформления. Ссылка на переводчик хранится в модуле: QApplication держит его слабо, и без этого сборка мусора вернула бы английские строки. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
