dbmole reported a hardcoded SERVER_VERSION of 0.1.0 while the package was
already published as 0.1.1: the constant had drifted because a bump has to
touch two places. Both servers now read the version from package.json
(resolveJsonModule + a JSON import attribute), so a release updates one
place and the reported version can no longer fall behind.
Add a dbmole guard test that add_connection publishes a non-empty
inputSchema with the expected required fields, mirroring esmole, so a future
`.superRefine` on the schema cannot silently empty it.
