v0.18.24: Share your checked tasks

Share image in Arena > Checked tasks turns your table into a 1200x630 card: one square per task (green = right), each model's score, speed and your GPU names. When your fastest model isn't the one that gets the most right, the card says both, e.g. "Fastest: ministral-3-3b, 228 tok/s, 8 of 15 right." No answers, prompts, paths or hosts on it.

15 tasks, one try each: a smoke test, not a benchmark.
