fix: Use dynamic import in check script for ESM package

kjonescertinia · kjonescertinia · commit af98f978a312 · 2026-04-26T09:06:35.000+01:00
The npm package is "type": "module", so the existing CommonJS require() in the check script throws ERR_REQUIRE_ESM on Node 20+. Switch to import() — works in both CJS and ESM contexts without --input-type. Caught by Codex review on #8.
