Werkdock's docker-compat branch names the verb for rootfs archives
'import' (docker import semantics) and keeps 'load -i --name' only as
a compatibility path. Werkator now runs 'werkdock import ARCHIVE IMAGE'
and falls back to 'load -i --name' on exactly the unknown-verb
signature (exit 125, 'unknown command' on stderr), so Werkator and
werkdock can be updated in either order. Any other import failure
propagates as before. The image name stays untagged: it equals
werkator-buildenv-<hash>:latest in werkdock's naming, and the existing
store needs no re-import. PR-doc under docs/prs/ with the PR#000
placeholder.
