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.

+# Quick Start Guide
+
+Get your Custom PHP Framework deployed quickly with this step-by-step guide.
+
+## Project Information
+- **Domain**: michaelschiemer.de
+- **Email**: kontakt@michaelschiemer.de
+- **PHP Version**: 8.4
+- **Framework**: Custom PHP Framework
+
+## Prerequisites
+
+- Linux/macOS/WSL environment
+- Internet connection
+- Sudo privileges (for dependency installation)
+
+## 1. First-Time Setup
+
+Run the setup script to install dependencies and configure the deployment environment:
+
+```bash
+cd deployment/
+./setup.sh
+```
+
+This will:
+- Install Docker, Docker Compose, and Ansible
+- Create configuration files from templates
+- Generate SSH keys for deployment
+- Validate the environment
+
+### Non-Interactive Setup
+
+For automated/CI environments:
+
+```bash
+./setup.sh --skip-prompts
+```
+
+## 2. Configure Your Environments
+
+Edit the environment files created during setup:
+
+```bash
+# Development environment
+nano applications/environments/.env.development
+
+# Staging environment  
+nano applications/environments/.env.staging
+
+# Production environment
+nano applications/environments/.env.production
+```
+
+**Important**: Replace all template values, especially:
+- Database passwords
+- SSL email addresses
+- API keys and secrets
+
+## 3. Test Your Configuration
+
+Validate your configuration without making changes:
+
+```bash
+# Using the deploy script
+./deploy.sh staging --dry-run
+
+# Using make commands
+make deploy-dry ENV=staging
+make validate-config ENV=staging
+```
+
+## 4. Deploy to Staging
+
+Deploy to staging environment for testing:
+
+```bash
+# Using the deploy script
+./deploy.sh staging
+
+# Using make command
+make deploy-staging
+```
+
+## 5. Deploy to Production
+
+When ready for production:
+
+```bash
+# Test production deployment first
+./deploy.sh production --dry-run
+
+# Deploy to production (requires confirmation)
+./deploy.sh production
+
+# Or using make
+make deploy-production
+```
+
+## Quick Commands Reference
+
+### Main Deployment Commands
+
+```bash
+# Deploy full stack to staging
+make deploy-staging
+
+# Deploy full stack to production
+make deploy-production
+
+# Dry run for any environment
+make deploy-dry ENV=production
+
+# Deploy only infrastructure
+make infrastructure ENV=staging
+
+# Deploy only application
+make application ENV=staging
+```
+
+### Status and Health Checks
+
+```bash
+# Check deployment status
+make status ENV=staging
+
+# Run health checks
+make health ENV=production
+
+# View application logs
+make logs ENV=staging
+```
+
+### Configuration Management
+
+```bash
+# Show deployment info
+make info
+
+# Validate configuration
+make validate-config ENV=production
+
+# Edit configuration
+make edit-config ENV=staging
+```
+
+### Emergency Commands
+
+```bash
+# Emergency stop all services
+make emergency-stop ENV=staging
+
+# Emergency restart all services
+make emergency-restart ENV=production
+
+# Create backup
+make backup ENV=production
+```
+
+## Deployment Flow
+
+1. **Validation**: Prerequisites, configuration, and tests
+2. **Infrastructure**: Ansible deploys security, Docker, Nginx, SSL
+3. **Application**: Docker Compose deploys PHP app, database, assets
+4. **Health Checks**: Validates deployment success
+
+## Safety Features
+
+- Production deployments require double confirmation
+- Database backups are created automatically
+- Dry run mode for testing without changes
+- Health checks verify deployment success
+- Emergency stop/restart commands available
+
+## Next Steps
+
+- Review [Environment Configuration](ENVIRONMENTS.md) for detailed setup
+- Check [Troubleshooting Guide](TROUBLESHOOTING.md) if issues arise
+- Customize Ansible playbooks for your specific needs
+- Set up monitoring and alerting for production
+
+## Support
+
+For issues or questions:
+- Check the troubleshooting guide
+- Review deployment logs
+- Verify configuration files
+- Test with dry-run mode first
+
+Happy deploying! 🚀
