Model Recommend Assemble

Model Recommend — Assemble the recommendation contract

The phase writes the normalized per-workload v2 input, then scripts/model_recommendation.py creates model-recommendation.json. The script output is the joint model/path contract; downstream phases consume it by workload id and do not rerank it. entries must be resolved and rerun before completion. When the user approves a live probe, separately writes ; recommendation acceptance never implies account invocability.
