Integrate community pelican runs from PRs #2 and #3; run variants

A combination can now ship multiple versions of the same case:
runs.<case-id> accepts an array, each extra variant naming its own
file; the viewer grows a RUN 01/02 switcher and validation enforces
distinct files plus a provenance note per variant.

Integrated content, attributed to their authors:
- Gemini 3.1 Pro + 3.5 Flash pelican runs from both PRs, shown as two
  variants each (PR #2's Google AI Studio runs first, PR #3's second)
- Doubao Seed 2.0 Pro / Mini pelican runs (folders renamed to the
  dash-only convention)
- GPT-5.5 Codex pelican run
