Update sibling cross-links: the 135M and 360M eval-only companion repos were consolidated into their deployable GGUF weight repos; point this negative-result card at the new URLs

Backfill sibling links to SmolLM2-135M and 360M eval cards (now published; both respond normally and anchor the 1.7B as uniquely anomalous)

Initial eval-only card: RYS sweep results for SmolLM2-1.7B-Instruct (negative result; v2 corpus)
