Town: client cells from their latest run; the backlog after a fresh village

decePub's e2e runs append to out/client.jsonl. The report kept the newest row per test and account, and the backlog
every row, so a failure from a run that picked other accounts stayed in both after later runs passed. Each client
cell now counts as its latest run left it (check.latest_client: the rows within an hour of its newest).

The backlog comes from a fresh village on today's build: 2556 checks pass and 4 fail, three of them peer-to-peer
counts, and one GoToSocial losing a status from its cache (an Update handled as a Create; a restart heals it),
recorded in INTEROP.md rather than as a gap, which would hide our own edits failing there. The community vote and the
Lemmy thread that failed before were data from older builds.
