- Add .github/workflows/ci.yml running `npm run verify` (lint, tests,
audits, builds) on every push to main and pull request, so regressions
can't reach main or a release tag unchecked.
- release.yml: use `npm ci` instead of `npm install` for reproducible builds.
- package.json: add `test` script aliasing the verify suite.
