Contributor credits, SVG prefetch, integrate Xiaomi MiMo from PR #4

- Runs gain a contributor field (GitHub username); the site renders an
  avatar chip linked to their profile next to each run's notes, and CI
  validates the field. All existing runs are attributed.
- SVG variants of a case are prefetched during idle time, so switching
  model tabs swaps images without a network hiccup.
- Xiaomi MiMo v2.5 Pro (Claude Code, max effort) integrated from PR #4
  with both case runs and provenance notes; README registry tables
  updated.
