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 Setup ohne Git
+
+## 1. App-Struktur vorbereiten
+
+### Option A: Bestehende App
+Falls du bereits eine App hast, stelle sicher dass sie diese Struktur hat:
+```
+deine-app/
+├── package.json          # Node.js Abhängigkeiten
+├── server.js             # Hauptdatei
+├── Dockerfile            # Docker-Konfiguration  
+└── ... weitere Dateien
+```
+
+### Option B: Neue App erstellen
+```bash
+# Erstelle App-Verzeichnis
+mkdir -p ~/meine-app
+
+# Beispiel Node.js App
+cd ~/meine-app
+
+# package.json
+cat > package.json << 'EOF'
+{
+  "name": "meine-app",
+  "version": "1.0.0",
+  "main": "server.js",
+  "scripts": {
+    "start": "node server.js"
+  },
+  "dependencies": {
+    "express": "^4.18.0"
+  }
+}
+EOF
+
+# server.js
+cat > server.js << 'EOF'
+const express = require('express');
+const app = express();
+const port = process.env.PORT || 3000;
+
+app.get('/', (req, res) => {
+  res.json({ 
+    message: 'Hello World!',
+    timestamp: new Date().toISOString()
+  });
+});
+
+app.get('/health', (req, res) => {
+  res.json({ status: 'ok' });
+});
+
+app.listen(port, '0.0.0.0', () => {
+  console.log(`Server running on port ${port}`);
+});
+EOF
+
+# Dockerfile
+cat > Dockerfile << 'EOF'
+FROM node:18-alpine
+WORKDIR /app
+COPY package*.json ./
+RUN npm install
+COPY . .
+EXPOSE 3000
+CMD ["npm", "start"]
+EOF
+```
+
+## 2. Ansible konfigurieren
+
+```bash
+# Ins Deployment-Verzeichnis
+cd ansible/netcup-simple-deploy
+
+# Konfiguration anpassen
+vim inventory/hosts.yml
+```
+
+**Wichtige Änderungen:**
+```yaml
+ansible_host: DEINE-NETCUP-IP        # ← Server IP
+domain: "deine-domain.com"           # ← Domain
+ssl_email: "deine@email.com"         # ← E-Mail
+local_app_path: "~/meine-app"        # ← Pfad zu deiner App
+```
+
+## 3. Deployment
+
+```bash
+# SSH-Key zum Server (falls noch nicht gemacht)
+ssh-copy-id root@DEINE-NETCUP-IP
+
+# App deployen
+make deploy
+```
+
+## 4. App updaten
+
+Nach Änderungen an deiner App:
+```bash
+# Einfach erneut deployen
+make deploy
+```
+
+Die Dateien werden automatisch zum Server übertragen und die App neu gebaut.
+
+## 5. Verschiedene App-Typen
+
+### PHP App
+```dockerfile
+FROM php:8.1-apache
+COPY . /var/www/html/
+EXPOSE 80
+```
+
+### Python Flask
+```dockerfile
+FROM python:3.9-slim
+WORKDIR /app
+COPY requirements.txt .
+RUN pip install -r requirements.txt
+COPY . .
+EXPOSE 3000
+CMD ["python", "app.py"]
+```
+
+### Static HTML
+```dockerfile
+FROM nginx:alpine
+COPY . /usr/share/nginx/html
+EXPOSE 80
+```
+
+## 6. Ordnerstruktur
+
+```
+netcup-simple-deploy/
+├── inventory/
+│   └── hosts.yml          # ← Hier konfigurieren
+├── deploy.sh              # ← Deployment starten
+└── Makefile              # ← Einfache Befehle
+
+~/meine-app/               # ← Deine App-Dateien
+├── Dockerfile
+├── package.json
+└── server.js
+```
+
+## 7. Troubleshooting
+
+### App startet nicht?
+```bash
+# Logs anschauen
+make logs
+
+# Container status prüfen
+ansible all -m shell -a "docker ps -a"
+```
+
+### Dateien werden nicht übertragen?
+```bash
+# Pfad prüfen
+ls -la ~/meine-app
+
+# Manuell testen
+ansible all -m shell -a "ls -la /opt/myapp/src/"
+```
+
+Das war's! Keine Git-Kenntnisse nötig - einfach deine Dateien bearbeiten und deployen! 🎉
