fix(test): enable Jest ESM for jose on Node 24+

NODE_OPTIONS=--experimental-vm-modules unblocks unit tests when jose is ESM-only; CI also listens on the active `dev` branch.

 ## [Unreleased]
 
+- Fixed Jest under Node 24+ for ESM-only `jose` by enabling `--experimental-vm-modules` in the test script.
+
 - Switched Rollup to `@rollup/plugin-typescript` so TypeScript builds on CI; regenerated `package-lock.json` for `npm ci`.
 - Pinned vulnerable transitive floors (`serialize-javascript`, `minimatch`, `js-yaml`, `brace-expansion`) and upgraded the ESLint toolchain.
+- Jest unit tests load CJS `dist` against ESM-only `jose` via `NODE_OPTIONS=--experimental-vm-modules` (Node 20+).
