Town: Iceshrimp.NET joins, and its mentions go nowhere new

Iceshrimp.NET 2026.1.2-beta runs in the pasture with AuthorizedFetch on;
its driver registers through the native API and takes Mastodon tokens from
its OAuth form. The pair passes 225 cells. A new Iceshrimp note reaches its
author's followers only, never an account it mentions or answers, until it
is edited (G-0004, peer): delivery cells now say when a server holds a post
only because it was addressed.

The checker credits a seeder's fetch to the object fetched, not to the reply
that needed it; the seeder skips the wait for an accept whose follow was
already accepted; the PrivaPub driver signs its roots in again when a run
reuses saved sessions.
