Pasture: Pixelfed and WordPress join

Pixelfed 0.14.4 (FrankenPHP with Horizon and the scheduler, on the shared
Postgres and Redis) and WordPress 6 with ActivityPub 9.3.1 (on a new shared
MySQL, WP-Cron run by a sidecar) are peers now, each with its scenario:
Pixelfed 26 checks (photos both ways with alt text, its place arriving as
Rome with its coordinates, comments, likes, a boost, edits and deletes),
WordPress 17 (an Article with its title, our reply, like and boost kept as
comments of their kinds, its edit and removal). Pixelfed has a town driver
and a pair spec: 145 checks pass, 2 expected (G-0007).

What they showed: Pixelfed names our posts by their page (fixed in
26dac40); on PostgreSQL its migration making caption nullable never runs,
so every remote boost failed (the pasture applies it); it files a DM it
fetches as followers-only (G-0007, upstream); Passport refuses a token
whose user id equals its client's id. WordPress signs with RFC 9421
first, which PrivaPub now verifies (c5a69d2).
