Switch to trusted publishing via OIDC (#47)

- Add id-token: write permission for OIDC trusted publishing
- Use Node 24 (ships npm 11.11.0, trusted publishing requires >=11.5.1)
- Add registry-url for OIDC auth flow
- Upgrade JS-DevTools/npm-publish from v1 to v4
- Remove NPM_AUTH_TOKEN (no longer needed)
