Модлоадер RustexRemake: агент, патч лаунчера, установщик и сборка

Моды грузятся через -javaagent, game.jar не патчится, переживают ре-обфускацию.

Что внутри:
- агент rsx-bridge.jar: профиль сборки игры, патчи A2/A6, загрузка модов
  через родной загрузчик игры (ilxq -> special.Main)
- патч лаунчера: окно выбора «С модами / Ванилла» по кнопке «Играть»
  и защита от автоапдейта лаунчера
- install/uninstall: всё ставится в %LOCALAPPDATA%\rsx-mod, пути не хардкодятся
- build: три готовых артефакта в dist, нужен только JDK
- testserver: локальный сервер, принимает любой ник и токен

Проверено на живом клиенте: мод грузится и выполняется в игровом потоке,
в логе видно игрока и мир.
