Both cards on the jobs tab start shut and read nothing until opened; a link
with ?run= opens the builds card. The fold-and-build-on-first-open part of the
hives card is now one LazyDisclosure, which the hives card uses too. Docs
follow.
/builds lists the builder's recent builds newest first, one card each with how
it ended, and opens a failed build's nix tail. /builds?run=<id> opens that
build's card and scrolls to it. The swarm-builder commit status now links
there instead of to the raw JSON record.
