Pasture: PeerTube joins, and its videos play through us

PeerTube 8.3.1 runs on the shared Postgres and Redis, transcoding off. Its
scenario passes 24 checks: a persona follows a channel; a new video comes as
the channel's Announce and reaches the persona's home as a boost, playable
through the media proxy with byte ranges; comments both ways thread; a like
and its undo count; renaming and deletion arrive; the unfollow; statistics.

The town's seeder also takes reruns on the same accounts in its stride: a
Lemmy community already made is found, a circle member already approved
asks nothing again.
