fix: clean skip for terramind_nyc on torchvision::nms

Same pattern as terramind_synthesis: when remote inference returns
non-ok or is unreachable AND local _ensure_adapter() raises the
torchvision binary-extension error, surface a clean 'skipped'
result with both root causes named instead of a noisy err.
