Docker image registry info API

Returns normalized Docker Hub tag metadata for an image reference: per-tag compressed size, architectures, OS, last-pushed time, and digest, plus a derived summary (total tags, newest tag, multi-arch flag, latest digest). The value-add is normalizing Docker Hub's deeply nested paginated tag API into one clean schema. Answers 'what tags does the nginx image have', 'is this image multi-arch', 'how big is the redis docker image', 'latest digest for grafana/grafana'.
