buildah writes STEP lines on stdout and its error on stderr, so the last line of both hid every image build's cause.
mesh-build-image's reason is now stderr's last lines (600 bytes) with the exit status, and the journal gets both tails;
mesh-build-node keeps stderr's end and stdout's start apart; mesh-build-go's cause skips go build's '# package' line.
writeLaunchers takes its entrypoint-to-launcher names from buildstep.Launchers, the rule the
controller reads a bundle by. RecipeSteps goes to 2: a member is now built against the SDK
its own lock names, which can change what a build produces (ADR 0405 §7).
After the build ended the module pushes the packed bundle with mesh-sdk's PushBlob under
<module>/<artifact> by its digest, a candidate's as a trunk build's, and the step answers
artifact-store://<module>/<artifact>/blobs/<digest> instead of the archive's path. A push
that fails fails the step not stored: <artifact>: <the store's words>; the packed bytes are
never written to the node. The manifest requires artifact-store and places its address.
