Implement core apt-ostree package management commands

- ✅ Added install <package> command with atomic operation messaging
- ✅ Added remove <package> command with atomic operation messaging
- ✅ Added upgrade command for system-wide atomic updates
- ✅ Added status command for system information
- ✅ Updated help text to show all available commands
- ✅ All commands compile and run successfully
- ✅ Release build working with optimized binary
- 🎯 Next: Implement actual OSTree integration for atomic operations
