ci: route PRs to workstream trackers and stop per-PR tracker comments

#1 had 329 comments and 215 linked PRs because every data PR closed #1
and got a tracker comment. Route by kind instead: releases and dumps ->
#1, new records -> #295, fixes -> #296, ci/app -> #297, site -> #19, and
keep a tracker the author already linked. The automatic tracker comment
now only fires for release PRs. The data summary counts all 12
categories.
