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.

+**Pasture evidence (2026-10-05, PeerTube 8.3.1, `tools/pasture/scenarios/peertube.sh`):** 24 checks pass:
+- a persona finds a channel (a group account) and its owner's account, and follows the channel (accepted at once);
+- a new video comes as the channel's `Announce`, not a `Create`, so it reaches the persona's home as the channel's boost
+  of the video, with a playable attachment served through the media proxy, which answers byte ranges;
+- a reply to the video is a comment on PeerTube, and an answer to that comment threads under the video here;
+- a like and its undo count on PeerTube; the video's renaming (`Update`) and its deletion reach us;
+- the unfollow, and statistics.
+
+PeerTube's own instance account announces each new video too, which we drop: nobody here follows it. Its users can
+follow only PeerTube-like channels and accounts, never a persona. It checks the `Host` header against its own name,
+without a port, before it gives out its OAuth client.
