Step-by-step for cutting the release-channel operator image on the FreeBSD build
host: sync clean merged heads (the gate requires it), build colibri + zot
artifacts, run BUILD_CHANNEL=release ISO_VERSION=0.10.0, verify provenance in
build-manifest.json, boot-proof via the acceptance runbook, and publish .xz.
Version-parameterized so future cuts just bump ISO_VERSION.
