dasandClaude Opus 5.5 5349a028c8 Fix issues found testing stage 5 in a VM
- Calamares branding takes the version from VERSION at ISO build time
- das-update tray hides its icon when updates were installed elsewhere
  (watches the xbps package database)
- Installer removes guest tools of other hypervisors; the live image
  starts VBoxClient only inside VirtualBox
- Live session no longer locks the screen while the installer runs
- das-tools 0.2.0, das-installer 0.2.0, das-settings 0.4.0
