🧹 Finaler Projekt-Cleanup - Alle unnötigen Dateien entfernt
🗑️ Entfernte Dateien: - Alle Backup-Dateien (*.backup_*) - Analyse-Report-Dateien (PROJEKT_ANALYSE_*, REDUNDANZ_*, etc.) - Ungenutzte Templates (404.html, 500.html, analytics.html, etc.) - package.json/package-lock.json (unnötig für Python-Projekt) - Temporäre Cleanup-Scripts 📊 Projektzustand nach vollständiger Bereinigung: - Projektgröße: 213MB (optimiert) - Stammverzeichnis: nur noch essentielle Dateien - Keine temporären/Backup-Dateien mehr - Saubere, produktionsreife Struktur ✨ Das MYP-Backend ist jetzt vollständig optimiert und bereit für Production! 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
