Each build.json now lists only the changes since the build published before
it, so it no longer grows with every release. history.json, written beside
latest.json, names every build folder; the updater reads the build.json of
each build between its own and the newest for its platform (at most 20, in
parallel), verifies each signature, and sums their changes, a commit counting
once from the newest build listing it so the older cumulative builds do not
double up. Past the cap, or where a build is missing or does not verify, the
summary and list end in "and more". latest.json is unchanged for older apps,
which list only the newest build's changes.
