Terminal: Das prompt, dprompt and dbanner (0.9.1)

- das-shell 0.1.0: the Das two-line bash prompt by default (replaces the PS1 of Void's skel .bashrc once), dprompt (Textual prompt builder with presets and live preview) and dbanner (SSH login banner editor: canvas tools, fields with values, widgets, das-banner service for cached ones, Das OS logo and tryzub pictures). Python tests in make test. - das-server 0.3.0 depends on das-shell; the server installer mentions dprompt and dbanner; the desktop image includes it. - run-qemu.sh forwards the guest's SSH to localhost:2222. - Hardware fixes: Ventoy menu icon, boot menu titles "Das OS <version>".
