clap requires --version with --download-base-url

Error message

clap requires --version with --download-base-url

What it means

Invariant expect in build_only_sdist: clap's `requires` chain (--sdist-out requires --download-base-url requires --version) guarantees --version is present when this code runs, so the unwrap cannot fail unless the clap definitions drift from this assumption. Internal consistency guard only.

Solutions

1. Keep the clap requires chain aligned with the expects here
2. Cover the build-only sdist path with a CLI test passing all required flags
3. Report as an internal bug in dbt-ci publish
