Name the build agent where genesis needs the module that builds (hq issue 596)

The beds checked the catalogue for builder/module.json before running genesis and the mesh beds held
'builder' among a raised mesh's modules; the catalogue retired builder for build-agent on 2026-10-03
(ADR 0190), so every genesis bed stopped before the installer ran.
