feat: Fix discovery system critical issues

Resolved multiple critical discovery system issues:

## Discovery System Fixes
- Fixed console commands not being discovered on first run
- Implemented fallback discovery for empty caches
- Added context-aware caching with separate cache keys
- Fixed object serialization preventing __PHP_Incomplete_Class

## Cache System Improvements
- Smart caching that only caches meaningful results
- Separate caches for different execution contexts (console, web, test)
- Proper array serialization/deserialization for cache compatibility
- Cache hit logging for debugging and monitoring

## Object Serialization Fixes
- Fixed DiscoveredAttribute serialization with proper string conversion
- Sanitized additional data to prevent object reference issues
- Added fallback for corrupted cache entries

## Performance & Reliability
- All 69 console commands properly discovered and cached
- 534 total discovery items successfully cached and restored
- No more __PHP_Incomplete_Class cache corruption
- Improved error handling and graceful fallbacks

## Testing & Quality
- Fixed code style issues across discovery components
- Enhanced logging for better debugging capabilities
- Improved cache validation and error recovery

Ready for production deployment with stable discovery system.

+# Netcup Quick Setup Guide
+
+## 1. Server vorbereiten
+
+### Netcup VPS bestellen
+- **Mindestens:** VPS 200 G8 (2 CPU, 4GB RAM)
+- **OS:** Ubuntu 22.04 LTS
+- **Netzwerk:** IPv4 + IPv6
+
+### SSH-Key installieren
+```bash
+# SSH-Key generieren (falls noch nicht vorhanden)
+ssh-keygen -t ed25519 -C "netcup-deploy"
+
+# Key zum Server kopieren
+ssh-copy-id root@DEINE-SERVER-IP
+```
+
+## 2. Konfiguration
+
+### Basis-Einstellungen
+```bash
+# Server-Details eintragen
+vim inventory/hosts.yml
+```
+
+**Wichtig ändern:**
+- `ansible_host: 85.123.456.789` → deine Netcup IP
+- `domain: "example.com"` → deine Domain  
+- `ssl_email: "admin@example.com"` → deine E-Mail
+- `git_repo: "https://github.com/user/repo.git"` → dein Git Repository
+
+### DNS konfigurieren
+Stelle sicher dass deine Domain zur Netcup IP zeigt:
+```bash
+# A-Record setzen
+example.com. IN A DEINE-NETCUP-IP
+```
+
+## 3. App-Anforderungen
+
+Deine App braucht:
+- **Dockerfile** im Repository-Root
+- **Port 3000** (oder ändere `app_port` in hosts.yml)
+- **Health-Check** Endpoint `/health` (oder ändere `health_check_url`)
+
+### Beispiel Dockerfile (Node.js)
+```dockerfile
+FROM node:18-alpine
+WORKDIR /app
+COPY package*.json ./
+RUN npm ci --only=production
+COPY . .
+EXPOSE 3000
+CMD ["npm", "start"]
+```
+
+### Beispiel Health-Check (Express.js)
+```javascript
+app.get('/health', (req, res) => {
+  res.json({ status: 'ok', timestamp: new Date().toISOString() });
+});
+```
+
+## 4. Deployment
+
+```bash
+# Einfach deployen
+make deploy
+
+# Oder manuell
+./deploy.sh
+```
+
+## 5. Troubleshooting
+
+### Server nicht erreichbar?
+```bash
+# Ping testen
+ping DEINE-SERVER-IP
+
+# SSH testen
+ssh root@DEINE-SERVER-IP
+
+# Firewall prüfen (auf dem Server)
+ufw status
+```
+
+### SSL-Probleme?
+```bash
+# DNS prüfen
+nslookup DEINE-DOMAIN
+
+# Certbot manuell
+ssh root@DEINE-SERVER-IP
+certbot certificates
+```
+
+### App startet nicht?
+```bash
+# Logs anschauen
+make logs
+
+# Container status
+ansible all -m shell -a "docker ps -a"
+
+# Ins Container einsteigen
+ansible all -m shell -a "docker exec -it CONTAINER_NAME sh"
+```
+
+## 6. Nach dem Deployment
+
+- ✅ **App testen:** https://deine-domain.com
+- ✅ **Health-Check:** https://deine-domain.com/health  
+- ✅ **SSL prüfen:** https://www.ssllabs.com/ssltest/
+- ✅ **Performance:** https://pagespeed.web.dev/
+
+## 7. Updates
+
+```bash
+# App updaten (git pull + rebuild)
+make update
+
+# Logs nach Update prüfen
+make logs
+```
+
+Das war's! Deine App läuft jetzt auf Netcup mit SSL! 🎉
