Package airflowmetadata defines the airflow-metadata manifest wire shape shared between the producer (a bundle binary's --airflow-metadata flag, emitted from pkg/execution) and the consumer (airflow-go-pack, which decodes it and renders the embedded airflow-metadata.yaml).

Package bundlefooter implements the AFBNDL01 trailer described in ADR 0004 (and task-sdk/docs/executable-bundle-spec.rst).
