Relays: PrivaPub reads from the relays its configuration names

Federation:Relays names relays by their actor (or inbox) address; the instance actor follows Public at each, as Mastodon
subscribes, a minute after start and every six hours (asked again a day after no answer or a refusal, undone when a
relay is no longer named). What an accepted relay passes on comes to the federated timeline and nobody's home: a public
post it forwards (Activity-Relay), read again from its origin like any forwarded post, and a post it announces
(aode-relay), kept as its author's and never as the relay's boost. Nothing of a persona's is sent to a relay; sending
public posts there waits for the owner.

The pasture gains both relays (peers/relay.sh, peers/aoderelay.sh) and scenarios/relay.sh, 13 checks. The village
backlog is clean: 2574 checks pass, one known gap (Misskey's).

+# and a public post of a Mastodon account nobody here follows reaches PrivaPub's federated timeline through the relay;
+# nothing of a persona's goes to a relay. Mastodon leaves each relay after, so the town sees no relayed posts. Needs the
+# relay, aoderelay and mastodon peers.
