Refactor hdmistat to use dependency injection and fix linter issues

Browse Source 
Major changes:
- Converted all cobra commands from global variables to CLI struct methods
- Eliminated global logger variable in favor of dependency injection
- Fixed all errcheck linter issues by properly handling errors
- Fixed Makefile to check formatting instead of modifying files
- Integrated smartconfig library for configuration management
- Added CLAUDE.md with project-specific development guidelines

Key improvements:
- All commands (daemon, install, status, info) now use CLI struct methods
- Logger is injected as dependency through fx providers
- Proper error handling for all DrawText and file.Close() calls
- Configuration loading now uses smartconfig with proper defaults
- Fixed formatting check in Makefile (make test no longer modifies files)

Technical details:
- Created CLI struct with log field (renamed from logger per request)
- All command constructors return *cobra.Command from CLI methods
- Config package uses smartconfig.NewFromAppName() correctly
- Fixed all critical errcheck issues throughout the codebase
- Maintained backward compatibility with existing functionality

All tests passing, code formatted, and ready for deployment.
