fix: исправить навигацию клавиатуры в TUI через GlobalKeyboardService

- Добавить GlobalKeyboardService — выделенный поток с блокирующим
  Console.ReadKey, единственный источник клавишных событий для TUI
- Убрать FocusManager из App.razor: перехватывал Tab до компонентов
- Удалить @onkeydown с <Select>: RazorConsole не пробрасывает Tab/стрелки
  через этот механизм
- Использовать FocusedValue вместо Value в Select для корректной подсветки
- Обновить CLAUDE.md и AGENTS.md: архитектура TUI, RazorConsole gotchas
- Добавить docs/tui_log.md: разбор проблемы и справочник по RazorConsole
