the builds list keeps the swarm's deploy builds too

build_meta, the build of each agent from internal/meta before a deploy, now
writes its result into the same list as the config PR builds: the agent, the
internal/meta commit, how it ended and what nix printed. The builds card titles
them by agent and shows them with the PR builds.
