review(8.3): send_to_builder turn 1 — widget integration tests contract

8.3 contract for paperboy-widget/tests/widget.integration.test.js: 5 jsdom-driven tests against the BUILT dist/paperboy-widget.min.js bundle covering selector resolution, overlay/inline rendering, copy-to-clipboard, and localStorage view persistence (plus restore-on-reload as a 5th case). Per-file '// @vitest-environment jsdom' pragma keeps the existing turndown unit test in Node env. APPROVED devDep additions: jsdom (^25.0.0; spec explicitly names jsdom) + scripts.test changed to 'npm run build && vitest run' to match converter/cli.
