Town: Pleroma joins, and a rerun finds what it made

Pleroma 2.10.2 runs in the pasture from its OTP release (libvips, the
dedupe question, and hackney pointed at the system CA bundle); its driver is
Akkoma's on its own container and database. The pair passes 241 cells, after
its first run showed Pleroma dropping Follows it could not verify yet.

The PrivaPub driver finds the group an earlier run made instead of failing
on the name; the seeder posts a quote or reply of a post from its own round
after that post.
