Replace install -D with mkdir -p + install for macOS portability,
add vitest with jsdom and testing-library, configure eslint for
react-hooks v7 warnings, and add tokio test deps for Rust.
Set up Vite + React 19 + TypeScript, Tauri v2, Tailwind v4,
shadcn/ui (dark theme), and all core frontend dependencies
(Zustand, TanStack Query/Table/Virtual, CodeMirror, lucide-react).
