Introduce first-time user onboarding and a navigable on-screen keyboard, plus persistent user storage via a bundled rusqlite database and Tauri API. Backend: add rusqlite dependency, DB initialization in tauri setup, schema migration/backfill for users, and two Tauri commands (get_first_user, create_user) with input sanitization and structured UserRecord. Frontend: add core/users.js (invoke + localStorage fallback), integrate user state initialization, add user setup view/styles and keyboard overlay (JS/CSS), wire views and navigation to show onboarding when needed, and update lock view behavior to coordinate onboarding and passkey flow. Also add @tauri-apps/api dependency and update package/Cargo lock files accordingly.
Introduce a working v0 Nebula Shell prototype (Tauri frontend) and redesign docs. Adds a complete frontend under src/ (views: home, lock, library, settings, overlays), core adapters (input, nav, passkey, router, state), global styles and shell guidelines, and view-specific HTML/CSS/JS. Update README with prototype notes, install/run/build instructions and controller testing tips. Update package.json to add dev/build scripts and add @nebulaproject/core as a dependency. Also include a detailed REDESIGN_DOCUMENTATION.md describing the Xbox-inspired horizontal dashboard, component patterns, and developer notes.
