Add measured output-agreement (0.98 cosine, ~13% rel-L2) to verification

Rigor: state explicitly this is not bit-identical; precise 79/80 vs 80/80 wording

Rework as pitch: headline comparison + plain-terms 'why it's better'

License: reflect CC-BY-4.0 base + add attribution section

Add 'why this matters on a real robot' section

README: full comparison ladder + FLOPs + resolution Pareto + honest eval-speed note

WorldDiT-Fast: ~2.6x fewer FLOPs / ~10x lower latency inference recipe, verified
