The Flux release renderer now accepts an expected-consumer set per
workload (chat may carry the HUX sidecar as a second consumer of the
exact same WebUI image) and binds HUX_IMAGE_TAG/HUX_IMAGE_DIGEST env
metadata to the released tag and digest when those fields are present.
Rendering fails when the binding fields are incomplete, keeping the
image identity single-sourced. Tests adapt to both topologies.
