[feat]: Cosmos3 DiT skeleton (Cosmos3VFMTransformer + Cosmos3LanguageModel)
Ports math (compute_mrope_position_ids_text/_vision, patchify, unpatchify) verbatim from vllm-omni transformer_cosmos3.py:113-177,1009-1036. Module tree (language_model.layers.*.self_attn.{q,k,v,o}_proj + gen_layers.*.cross_attention.* + vae2llm + llm2vae + time_embedder + norm_moe_gen) exposes the parameter names the checkpoint converter targets. All layer forward() raise NotImplementedError until weights publish; module instantiation + state-dict key tests pass.
