Add July 2026 world model curation updates

[iChubai]

Summary

• Add the July 4, 2026 curation pass to the README metadata.
• Integrate 29 strictly reviewed world-model papers across driving, robotics, navigation, WAMs, 3D/4D scenes, video simulators, JEPA, symbolic models, MBRL, planning, simulation/evaluation, agents, surveys, and benchmarks.
• Cross-check recent arXiv candidates and updates from peer awesome-world-model repositories, including the July 3 leofan90 update.

Curation notes

• Included papers that directly model future world state, action-conditioned dynamics, world-action behavior, simulator rollouts, planning/evaluation through learned worlds, or world-model benchmarks/surveys.
• Excluded weakly related or low-impact candidates such as generic video adaptation, scene-graph-only perception, narrow preliminary toy domains, unrelated cloud/code-generation systems, and non-world-model engineering papers.

Validation

• git diff --check
• node scripts/check-arxiv-duplicates.mjs README.md
