Apple Container removes containers when they stop, making the
stop-then-export flow impossible regardless of the --rm flag.
Replace `container export` (requires stopped container) with
`container exec --user root <name> tar --create ... --file=- --directory=/ .`
streamed to a temp file, then build the committed image from that archive
as before. The bottle stays running after commit, which is better UX.
Drop the stop-confirm prompt from MacosContainerFreezer since we no longer
need to stop the container at all.
