- Added urfave/cli/v2 dependency for better CLI structure
- Created modular command structure with separate files:
- common.go: Shared utilities and client setup
- cmd_discover.go: Device discovery commands
- cmd_info.go: Device information commands
- cmd_volume.go: Volume control commands
- cmd_playback.go: Playback control commands
- cmd_source.go: Source selection commands
- Replaced giant main() function (complexity 149) with organized subcommands
- Added proper flag handling and validation
- Improved help text and user experience
WIP: Some issues remain (flag conflicts, missing commands)
Next: Complete remaining commands and fix conflicts
