Reuses the clone script's vzdump/relay/restore flow but as a move rather
than a copy: preserves the original MAC by default, adds a stop-source/
start-target cutover step, and an opt-in --remove-source to destroy the
source guest afterward. Not a true qm migrate (nodes aren't clustered),
so the default --mode snapshot has a documented write gap between
snapshot and cutover; --mode stop avoids it at the cost of downtime.
