unkinben c129a09541 fix: resolve HEAD requests from metadata without streaming the body ...

Docker HEAD routes ran a full Fetch + io.Copy, downloading the whole blob
(and fetching upstream on a miss) only for net/http to discard the body.
Add Engine.Head, which answers cached artifacts/indexes from store
metadata and otherwise issues an upstream HEAD, and route HEAD to a
dedicated handler that writes headers only.
