feat: vmtest.sh runs everything: boot loaders plus the cli, menu, hw, installer and toggles suites

vmtest.sh [--install] [--window] [--screen] [boot|loader|suite...], a detached screen
session with --screen, the summary in ~/vms/last-test.txt, the rows that need a person
listed as SKIP. New: the installer suite (R2.1), the toggles suite (R1.8) and H3 (BIOS
dry-run, per-block '# env:' for the VM start). vmsuite.sh and vmbootloadertest.sh are
executable again.
