## Smoke-Test Beschreibung

### Backend
- In-memory SQLite (`:memory:`) wird via `SqliteAdapter` initialisiert
- Fastify `app.inject()` simuliert HTTP-Requests ohne echte Netzwerkverbindung
- Auth-Flow vollständig getestet: Register → Login → Me → Password Change → Logout
- Project CRUD vollständig getestet: Create → List → Get → Update → Delete
- Health Endpoint gibt `{ status: 'ok', timestamp: ISO-String }` zurück

### Frontend
- SpatialIndex: rbush-basierte räumliche Suche mit insert/search/remove/clear/bulkInsert
- LayerManager: Layer-Verwaltung mit add/remove/toggle/tree/filter/duplicate
- HistoryManager: Undo/Redo-Stack mit initialize/push/undo/redo/jumpTo/subscribe/maxStackSize
- jsdom environment für DOM-abhängige Tests aktiviert

## Coverage

### Backend
- Auth CRUD: Register, Login, Logout, Me, Password-Change → alle Endpoints getestet
- Project CRUD: List, Get, Create, Update, Delete → alle Endpoints getestet
- Health: GET /api/health → getestet

### Frontend
- SpatialIndex: insert, bulkInsert, search, remove, clear → alle öffentlichen Methoden
- LayerManager: alle 18 öffentlichen Methoden getestet
- HistoryManager: initialize, pushSnapshot, undo, redo, canUndo, canRedo, getHistory, jumpTo, clear, subscribe, getUndoCount, getRedoCount → alle öffentlichen Methoden

## Verbotene Patterns Check
- ❌ Keine echten Netzwerk-Verbindungen → ✅ Nur `app.inject()`
- ❌ Keine echten WebSocket-Verbindungen → ✅ Keine WebSocket-Tests
- ❌ Keine Datei-Schreiboperationen auf echte DB-Files → ✅ Nur `:memory:`
- ❌ Keine Mock-Libraries außer vitest built-in `vi` → ✅ Nur vitest built-ins
