 - `.github/workflows/publish.yml` — on push to `main` (or manual dispatch) it runs

   not already on the registry**. So a commit that bumps the version (`npm version patch`)

 - In CI the live integration/MCP tests auto-skip (no cached session → no network), so `npm test`
   runs the unit suite only.
