Patch Changes a7dd893: Add experimental evaluation model aliases and registry resolution. `customProvider` accepts `evaluationModels`, registries expose `evaluationModel`, and `experimental_evaluate` accepts string IDs when an evaluation-capable default provider is explicitly configured. Evaluation never implicitly falls back to Gateway. Model-resolution errors now identify `evaluationModel` while stable provider contracts remain unchanged.
