build: extend the main-sync gate to the image build and the k8s deploy
Same hazard as the package build, with the cluster on the receiving end: a
branch behind main builds images missing whatever landed there, and deploy-k8s.sh
pins that sha in Pulumi — making the stale build the cluster's source of truth.

build-mcpd.sh gets its own call because it is run standalone as well as from
deploy-k8s.sh, so neither can rely on the other having checked.

`--dry-run` is exempt. It builds and cuts over nothing, and blocking a read-only
inspection is exactly what teaches people to export MCPCTL_ALLOW_BEHIND_MAIN=1
permanently — which would disable the gate for the real deploys too.

The failure text is now artifact-agnostic ("produce an artifact" / "shipping
it"), since one helper now speaks for packages, images and deploys.

Verified against a synthetic ref one commit ahead: build-mcpd.sh exits 1 before
any docker work, and deploy-k8s.sh exits 1 before the test gate, the pg_dump,
the image build and pulumi. Neither the working tree nor HEAD was moved to test
this — the ref was built with git commit-tree and deleted afterwards.
