feat: Add machinectl management and backup/restore system

- Create cfg/aios-ctl.zsh with machinectl control commands
  - aios-start/stop/shell/login for basic operations
  - aios-backup to save current state to aiosback
  - aios-reset to restore from backup (preserves config files)
  - aios-update to update packages in backup
- Create cfg/install.sh for automated installation
  - Extracts tarball to /var/lib/machines/aios
  - Creates systemd-nspawn configuration
  - Automatically creates initial backup image (aiosback)
- Include aios-ctl.zsh in container at /opt/aios-ctl.zsh
- Include install.sh in tarball for easy deployment
- Config files in ~/.config/syui/ai are bind-mounted and preserved across resets
