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.
- Change '// Output:' to '// Example output:' in all examples
- Examples will still appear in pkg.go.dev documentation
- Prevents examples from running as tests and trying to connect to real devices
- Examples are for documentation purposes, not runtime testing
- Fix GetInfo() to GetDeviceInfo() in client examples
- Update discovery examples to use proper constructor patterns
- Fix Volume.Muted to Volume.MuteEnabled field reference
- Correct DiscoveredDevice field names (remove non-existent MACAddress)
- Fix ZoneMember to use IP field instead of IPAddress
- Update Presets examples to use Preset slice and proper methods
- Replace non-existent SubscribeToEvents with NewWebSocketClient pattern
- Fix Capabilities to use Capability field instead of Sources
- Remove duplicate example function names
- Ensure all examples compile and use correct API surface
- Add root package documentation with quick start guide and feature overview
- Enhance client package with detailed usage examples and API coverage
- Add comprehensive discovery package documentation with protocol explanations
- Create models package documentation explaining all data structures
- Add extensive example functions for all major use cases:
* Basic device control and playback
* Volume, bass, and balance management
* Source selection and preset handling
* Multiroom zone management
* Real-time WebSocket event monitoring
* Device discovery with UPnP and mDNS
* Error handling and context cancellation
- Include code examples for pkg.go.dev's example rendering
- Document API endpoints, data structures, and best practices
- Add hardware compatibility and implementation notes
