Print '[vm create] ready in <elapsed>' to stderr once the create
operation completes successfully. Surfaces how long the full
create-to-ready cycle took (image resolve + work disk + boot +
guest agents + capability post-start), which the per-stage
progress lines don't add up to in any visible way.
Format adapts to scale: sub-second prints as 'NNNms', sub-minute
keeps one decimal ('4.7s'), longer prints as 'MmSSs'. Always
emitted (not gated on TTY) so logged and CI output carry the
number too.
