Boot menus now default to "boot from local disk" instead of the
destructive auto-install entry -- the earlier version would have run
the destructive install automatically on a timeout with no action
taken, backwards from the intended safety gate.
early-command-test-FAILED.sh is kept as-is (not wired into the seed)
purely as a record of what was tried: d-i preseed/early_command never
executed at all under Ubiquity, see ADR-0009's 01.08.2026 update for
why (Ubiquity's own Python plugin architecture has no hook for it).
