Replace the "see zot/README" placeholder with the canonical build invocation
that clawdie-iso's preflight prints:
git checkout v0.2.29
GOOS=freebsd GOARCH=amd64 go build -trimpath -o bin/zot ./cmd/zot
Output must land at <zot>/bin/zot (the ISO default artifact dir); the checked-
out ref becomes ISO_VERSION via git describe. Add the zot/agent build overrides
(ZOT_REPO, ZOT_ARTIFACT_DIR, COLIBRI_STAGE_AGENT) and the zot binary to the
preflight checklist.
