// Image Generation Model Identifiers
// Used to detect if a model is an image generation model (not text generation).
// `isImageGenerationModel(name)` (below) does boundary-aware matching:
// the modelName must equal an entry OR contain an entry followed by a
// non-alphanumeric character (`-`, `_`, `:`, `/`, `.`, end-of-string).
// This prevents short identifiers like `"V_1"` or `"gpt-image-1"` from
// accidentally matching unrelated model names that happen to embed them.
