feat: внедрение RazorConsole TUI с runtime-управлением MCP-инструментами

- Добавлен RazorConsole.Core для интерактивного TUI-дашборда
- ToolRegistryService: живое включение/отключение модулей и отдельных методов
- InMemoryLogSink: кольцевой буфер логов с фильтрацией по модулю
- TUI: 3 таба (Overview, Logs, Settings)
- IToolModule: generic-интерфейс для легкого добавления новых MCP-модулей
- Guard-проверка TryCheckEnabled() во всех существующих инструментах
