Hugging Face sign-in, submitter profile links, and three scored axes

Entries are tied to a Hugging Face account and the submitter's handle links to their profile. Scoring carries three axes: oxidation window 40, lithium-metal stability 35, use novelty 25. The lithium pathway is an entry condition rather than a scored axis. Reference materials and the frozen reference distribution are rebuilt to match.
