No test project: PrivaPub.Tests goes, and neither CI nor the deploy runs tests

Owner decision 2026-10-17: the tests took about 22 of a release's 25 minutes on the runner (9 in build.yml after a push,
12 more in deploy.yml on the tag, for the same commit). PrivaPub.Tests is deleted with tools/ci/with-test-mongod.sh;
build.yml builds and deploy.yml publishes. CLAUDE.md's Testing section becomes Verifying (build, run locally, the
pasture), and the invariants no longer name the tests that checked them. decePubClient's tests/e2e goes too, so the
pasture's peers/decepub.sh serves a plain publish with the Pasture environment (decePubClient/publish/wwwroot).

 | Crawler | **On in production**, seeded with a handful of large servers of different kinds (`appsettings.Production.json`); the deploy fails if `/stargazing` does not say it is on. |
 | Sign-up | **Closed: invitations only.** A group invitation creates an account; open sign-up answers 403. NodeInfo, `/api/v1/instance` and `/api/v2/instance` read the same switch (`Registrations:Mode`), and the deploy fails if they disagree. The first login on a server is made from the client's setup page while no administrator exists (2026-10-16: first come, first served, no setup code); it becomes the administrator with its first persona, and setup closes for good (`ServerSetup`, kept across restores). `PrivaPub admin create-root` remains the way in from the box. |
 | Signed-in smoke check | **Dropped (2026-10-17).** It was `@thepra`, undiscoverable, made and kept by the deploy under the root `deploy-smoke`. The owner took `@thepra` for the administrator's login (`PrivaPub admin move-persona thepra <root>`), `deploy-smoke` was deleted (`admin delete-root`), and the deploy keeps only its anonymous checks. |
