binaries property
Binaries selects the ARTIFACT lane (artifact.go): build what the repo's hanzo.yml binaries: block declares — a Go binary, an npm tarball, a Rust binary — and publish it to hanzoai/s3 instead of pushing an image. It is the same recipe hanzoai/ci reads, sent verbatim, so image is meaningless here and must be absent.
Implementation
List<BinarySpec> binaries;
