stefan 9282dd0eb4 refactor: Migrate from monolithic to modular architecture
1. **Dokumentation der Architektur:**
    - Vervollständigen Sie die C4-Diagramme im docs-Verzeichnis
    - Dokumentieren Sie die wichtigsten Architekturentscheidungen in ADRs

2. **Redis-Integration finalisieren:**
    - Implementieren Sie die verteilte Cache-Lösung für die Offline-Fähigkeit
    - Nutzen Sie Redis Streams für das Event-Sourcing
