Implementiere robuste JSON-Fallback für SQLite-Datenbankprobleme
- Füge JSON-Fallback-Datenbank hinzu als Alternative wenn SQLite-Bindings nicht kompilieren - Verbessere Startup-Skript mit automatischem SQLite-Rebuild beim Start - Füge Fehlerbehandlung und Logging für Datenbankprobleme hinzu - Aktualisiere Migrationsskript, um beide Datenbanktypen zu unterstützen - Ersetze fehlerhaften npx-Install im Dockerfile (bereits in Node enthalten) 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
