"""Установка модпаков CurseForge (zip с manifest.json).

Формат CurseForge (minecraftModpack): в архиве лежит manifest.json, где

указана версия Minecraft, загрузчик и список модов (projectID + fileID),

плюс папка overrides/ с готовыми файлами игры.
|

Старые сборки (minecraftInstance) содержат minecraftinstance.json — там

моды перечислены с готовыми downloadUrl. Поддерживаются оба формата.
