A private fediverse on the workstation: PrivaPub against a real GoToSocial

tools/pasture/run.sh starts PrivaPub, GoToSocial and Mongo on one podman network behind Caddy's internal CA, and
interop.sh drives both through their own client APIs: follows (one to a locked account), posts, CW, replies, likes,
boosts, DMs, edits, deletes and unfollow. All 25 checks pass, three fresh runs in a row.

- Federation:AcceptAnyCertificate joins the two test-network switches; startup refuses all three in Production.
- WebFinger falls back to http only when AllowPlainHttp is on.
- A bootstrap logger, so a failure before the host is built is no longer silent.
- P4 is ticked in the roadmap, with what has not been run live (Lemmy, a Mastodon circle member).

+- **Two sites on one podman network, one Caddy in front.** `privapub.test` and `gts.test` are network aliases of the
+  Caddy container, which serves both with its internal CA (`tls internal`). Both servers are told to accept any
+  certificate: PrivaPub through `appsettings.Pasture.json`, GoToSocial through `GTS_HTTP_CLIENT_TLS_INSECURE_SKIP_VERIFY`.
+  GoToSocial WebFingers and fetches over https only, so plain http between them is not an option.
+- From the workstation, PrivaPub's API is `http://127.0.0.1:6971`. GoToSocial is reached as `https://gts.test:6443`
+  with `curl -k --resolve gts.test:6443:127.0.0.1`, because its sign-in cookie is bound to the host name.
+- **GoToSocial's cached home timeline can stop taking new posts after its first read**, its owner's own included, while
+  a `min_id` query shows them all. So a delivery is checked by looking the object up by URI with `resolve=false`
+  (`on_gts`), which answers from GoToSocial's database and never fetches from us. A home-timeline check there proves
+  nothing, in either direction. A deleted status still turns up in that search as a "deleted status" stub, so a delete
+  is checked as a 404 on `/api/v1/statuses/{id}`.
+- **GoToSocial creates its accounts locked**, so `interop.sh` approves alice's request through
+  `/api/v1/follow_requests`. That also checks our pending (`requested`) state and the manual Accept.
+- The scenario covers:
+  - discovery and follows both ways;
+  - posts and CW;
+  - a reply and its notification;
+  - likes and boosts both ways;
+  - DMs both ways, and the DM staying off public timelines;
+  - edit, delete both ways, and unfollow.
+- `run.sh up` replaces every container, Mongo included, so each run starts clean. To keep the data, republish into
+  `tools/pasture/.publish` and `podman restart pasture-privapub`; that is how a migration is tried on dirty data.
+
+After the pasture, verify.funfedi.dev and the owner's GoToSocial at social.arasaka.software. **Ask before acting from
