Skill: `.claude/skills/reui` (v `668fb463eb`); обновление: `curl.exe -fsSL https://mcp.reui.io/install | node -` из корня проекта.

+**Важно:** skill описывает текущий registry (в т.ч. data-grid на TanStack Table v9). Установленный в проекте `@reui/data-grid` может оставаться на v8 до явного CLI upgrade — не ломать kit без миграции.
