fix: address PR review feedback — broken link, NaN guard, zizmor tags, fork skip

- Remove broken Triton issue link from Dockerfile.benchmark.libero
- Add module-level _safe_int helper to guard n_episodes against NaN
- Move _safe_float to module level alongside _safe_int
- Add # zizmor: ignore[unpinned-uses] to all upload-artifact@v4 steps
- Add if: env.HF_USER_TOKEN != '' to Libero smoke eval for fork PRs
