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.

+# Deployment Backup Summary
+
+This directory contains the old deployment configurations that were moved during the modernization of the deployment system.
+
+## Moved Directories
+
+### ansible/
+**Original Location**: `/ansible/`  
+**Contents**: Multiple Ansible deployment configurations
+- `netcup-simple-deploy/` - Basic server deployment setup
+- `nginx-cdn-germany/` - CDN and Nginx configuration for German servers
+- `wireguard-server/` - VPN server setup and client management
+
+**Key Features Preserved**:
+- Server setup automation
+- Nginx reverse proxy configuration
+- SSL certificate management
+- Multi-environment support (staging/production)
+
+### x_ansible/
+**Original Location**: `/x_ansible/`  
+**Contents**: Alternative Ansible setup with different structure
+- Complete playbook structure with inventories
+- Docker Compose integration
+- Environment-specific configurations
+- Deployment and setup scripts
+
+### ssl/
+**Original Location**: `/ssl/`  
+**Contents**: SSL certificates and keys for local development
+- `fullchain.pem` - Certificate chain
+- `privkey.pem` - Private key
+- `rootCA.*` - Root certificate authority files
+- `localhost.*` - Local development certificates
+
+**Note**: These certificates will be integrated into the new SSL management system in `deployment/configs/ssl/`
+
+### bin/
+**Original Location**: `/bin/`  
+**Contents**: Deployment utility scripts
+- `deploy` - Environment-specific deployment script
+- `setup` - Server setup script  
+- `up`, `down`, `restart` - Docker management scripts
+- `logs`, `test`, `check-env` - Utility scripts
+
+**Note**: Functionality from these scripts will be modernized and integrated into `deployment/scripts/`
+
+## Migration Path
+
+The new deployment system in `/deployment/` consolidates and modernizes these configurations:
+
+1. **Infrastructure** (`/deployment/infrastructure/`): 
+   - Consolidates Ansible playbooks from both `ansible/` directories
+   - Adds modern server configuration management
+   - Implements security best practices
+
+2. **Applications** (`/deployment/applications/`):
+   - Modernizes Docker Compose configurations
+   - Adds environment-specific optimizations
+   - Integrates health checking and monitoring
+
+3. **Scripts** (`/deployment/scripts/`):
+   - Modernizes and consolidates utility scripts from `bin/`
+   - Adds deployment orchestration capabilities
+   - Implements rollback and recovery features
+
+4. **Configs** (`/deployment/configs/`):
+   - Centralizes configuration templates
+   - Integrates SSL certificate management
+   - Adds monitoring and logging configurations
+
+## Recovery Instructions
+
+If you need to revert to the old deployment system:
+
+1. Stop any new deployment processes
+2. Move directories back from `.deployment-backup/` to their original locations:
+   ```bash
+   mv .deployment-backup/ansible ./
+   mv .deployment-backup/x_ansible ./  
+   mv .deployment-backup/ssl ./
+   mv .deployment-backup/bin ./
+   ```
+3. Update any references to the new deployment system
+
+## Preservation Notes
+
+- All original files are preserved unchanged
+- Directory structure maintained as-is
+- No modifications made to original configurations
+- Can be used for reference during new system development
+
+## Cleanup
+
+Once the new deployment system is fully tested and deployed, this backup directory can be removed. Recommended timeline: Keep for at least 30 days after successful production deployment of the new system.
