Major improvements to device discovery system:
🔧 **SSDP Discovery Fixed**:
- Fixed networking issue where SSDP used connected UDP socket instead of UDP listener
- SSDP now properly receives unicast responses from multicast requests
- UPnP discovery now works reliably and finds all MediaRenderer devices
✨ **Enhanced DiscoveredDevice Model**:
- Added consistent URL fields (APIBaseURL, InfoURL) for all discovery methods
- Added protocol-specific fields (UPnPLocation, UPnPUSN, MDNSHostname, etc.)
- Added DiscoveryMethod tracking to show how devices were found
- Added device merging support for same device found via multiple protocols
🚀 **Unified Discovery Improvements**:
- Fixed device merging logic to properly combine protocol-specific data
- Discovery methods now correctly show combinations like 'Configuration+SSDP/UPnP+mDNS/Bonjour'
- Removed duplicate configuration device loading in individual services
- All three discovery methods (SSDP, mDNS, Configuration) work together seamlessly
🛠 **Updated Tools & Examples**:
- Updated soundtouch-cli to display new consistent field structure
- Enhanced all example programs with better device information display
- Added new unified discovery example demonstrating all three methods
- Fixed context timeout issues in example programs
📋 **Comprehensive Testing**:
- All tests updated and passing
- Real-world validation with actual Bose SoundTouch devices
- Confirmed discovery methods properly merge device data
Every discovered device now has consistent http://host:port/info URLs regardless
of discovery method, while preserving valuable protocol-specific metadata.
- Implement HTTP client with XML support for SoundTouch Web API
- Add UPnP device discovery with SSDP protocol
- Create type-safe Go models for API responses
- Build CLI tool with device discovery and info commands
- Add comprehensive configuration management via .env and env vars
- Include extensive documentation (API endpoints, patterns, development guide)
- Translate all German documentation to English
- Set up modern Go project structure with testing framework
- Add Makefile for cross-platform builds and development workflow
