minor fixes

- Read version from bin/.version file (reliable, no JAR locking)
- Save version to bin/.version when downloading JAR
- Use getLauncherJar() for all JAR path references
- Create binDir in main()
- Remove build.version dependency completely

 ## Чего пока нет в лаунчере
 
+- Графического интерфейса (GUI) — только TUI
 - Нормальных настроек (пока доступна только настройка Java и выделенной оперативной памяти)
 - Поддержки **Forge** (в разработке)
 - Поддержки Quilt, LabyMod, NeoForge и других лоадеров
 - Раздела новостей об обновлениях Minecraft и лаунчера
 - Выбора готовых пресетов оптимизации JVM
+- Кастомных модов (UI, спавнеры, DPI, карточки)
+- Сайта для лаунчера и сервера
+- Трекинга наигранного времени
 
 ## Что планируется доработать в ближайшее время
 
+- **UI мод** — переписать мод на UI: красивое главное меню, анимации, анимированный задний фон, эмбиент звуки, интерактивность, урезание ванильных элементов до используемых
+- **GUI мод** — привести в единый стиль с главным меню
+- **Мод на спавнеры** — кастомные спавнеры с лимитами (5-15 спавнов), отслеживание спавнов вокруг, замена на базовый спавнер при достижении предела с эффектами и звуками, данжи «временного парадокса» с процедурной генерацией этажей, минибоссы, лут
+- **DPI мод** — отслеживание не-ZernMC лаунчеров, защита от форков с выпеленной проверкой, уведомления админу в Telegram с технической информацией
+- **Сайт** — полноценный сайт для лаунчера и сервера (текущий «полу-живой» нуждается в полной переделке)
+- **Система карточек** — дроп случайных карточек (обучена на датасете скинов CS2), просмотр, продажа, крафт, обмен между игроками, внутриигровая валюта «йоны», начисление йонов на баланс, обмен йонов на предметы, вывод йонов в отдельный предмет, анимации и эффекты
+- **Web API** — OpenAPI документация, уровни доступа к API (например, получение списка игроков требует проходку)
+- **Трекинг наигранного времени** — обновление каждую минуту вместо часа для нормальных графиков игроков
 - Генерацию команды запуска Minecraft
 - Стабильную работу автообновления лаунчера
 - Полноценные настройки
-- Стабильность и производительность серверной части
+- **Улучшенный античит / ClientChecker** — проверка подлинности клиента при подключении к серверу, без нужного клиента не пустит; поставляется вместе с лаунчером, не общедоступный. Хеш-проверка всех папок и файлов сборки при каждом запуске — при несовпадении одного хеша все моды переустанавливаются. Игнорируются только: логи, ресурспаки, шейдеры, сейвы, личные файлы. Защита от подмены libs и лоадеров (Meteor и аналоги), проверка целостности модов через хеши. В перспективе — защита от Mixin-атак (перехват логики других модов), сбор отчёта о текущей сборке и сравнение с базовой
+- **Баг-фиксы сервера:** подключить `admin_router` в `main.py`, исправить импорты ролей (`ROLE_USER` и др. не существуют в `roles.py`), добавить эндпоинт `/auth/pass/activate`, убрать дубли импортов (`TTLCache`, `Response`)
 - Улучшение прокси-режима
+- Стабильность и производительность серверной части
 - Общую надёжность загрузки файлов с сервера
-- аккаунты, проходки
 
 ## Важная информация перед использованием
 
@@ -39,12 +52,10 @@
 
 Лаунчер использует **текстовый интерфейс (TUI)**:
 
-- `W` / `S` (или `Ц` / `Ы`) — перемещение по меню  
+- `W` / `S` (или `Ц` / `Ы`) или `↑` / `↓` — перемещение по меню  
 - `ENTER` — выбор пункта  
 - `ESC` или пункт «Назад» — возврат назад
 
-> **Важно:** Стрелки ↑/↓ могут вызывать баги и краши. Используйте только `W`/`S`.
-
 Если вы случайно кликнули мышкой в окне лаунчера и он «заморозился» — просто нажмите **любую клавишу** на клавиатуре.
