Function ResolveModels

internal/providers/models.go:70–107

ResolveModels returns the model list to present for endpoint ep, identified by epName. Priority: 1. Built-in /v1/models discovery → combined with ep.Models. 2. ep.Models when API discovery fails or returns no models. 3. Deprecated ep.ListModelsCmd fallback when no static models exist. 4. No source
