v4.17.1

Fixed

• test/lib/detach/examples-integration.test.ts builds dist/ on demand. The detach examples-integration test runs each example via npx tsx, which resolves import { ... } from 'footprintjs' to the package's dist/index.js. CI runs npm test BEFORE npm run build, so dist/ didn't exist yet during the test — every detach example exited with Cannot find module .../dist/index.js and the v4.17.0 publish workflow failed before npm publish could run. A beforeAll hook now builds dist/ if missing (no-op locally where dist is already current). v4.17.1 is functionally identical to v4.17.0 — just makes the publish go through.
