Use Fly registry auth for Dockerless deploys Have the deploy script ask flyctl to mint the short-lived registry credentials that Fly expects, then pass those credentials to Skopeo through a temporary auth file. This keeps the NixCI deploy path Dockerless while avoiding raw token authentication issues against registry.fly.io. Add comments that explain the image build, temporary auth setup, registry push, and final image deploy steps.
