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).
