Release jobs could package and publish generated native or executable payloads
without a release-time signal if a packlist regression omitted a required file.
Add read-only verification jobs before each trusted-publishing job. They pack every
generated package, verify its declared literal payload files against the source
artifacts, and smoke-test the v11 plain-JS CLI, the v11 executable wrapper
with its native package, and the pnpr wrapper with its Linux native package.
Keeping the smoke tests outside OIDC-enabled publishing jobs prevents an
artifact executed during verification from obtaining a trusted-publishing token.
The verification tarballs live outside package directories so they cannot become
part of subsequently published archives.
