1.1.2 — one sentence, in all five places a reader meets it

1.1.1 changed the description in Cargo.toml and in the npm package and
missed pyproject.toml, which is the one maturin publishes. PyPI took the
old summary and neither registry lets that be edited afterwards, so the
correction needs a version of its own.

The two READMEs had drifted further than the description fields. A
registry page leads with the README rather than the summary, and npm's
opened by saying the package needs no network without ever saying it
covers the Byzantine Catholic churches — which is most of what the
sentence was changed to convey.

Five files now carry it, and a test reads all five and names the ones
that disagree. It was written against the mistake above and fails on it.

+- The published description says what the package covers, and says the same
+  thing in both registries. PyPI takes its summary from `pyproject.toml`, which
+  1.1.1 did not update, so it went out with the old one-line text while npm got
+  the new one. The two READMEs had drifted apart as well: npm's opened without
+  mentioning the Byzantine Catholic churches at all. All four now carry one
+  sentence, and a test fails if any of them moves without the others.
