--- Add gemini-3.1-flash-image mapping keys without wiping existing custom mappings.
+-- Add gemini-3.1-flash-image and gemini-3.1-flash-image-preview to model_mapping
 --
 -- Background:
--- Antigravity now supports gemini-3.1-flash-image as the latest image generation model.
--- Existing accounts may still contain gemini-3-pro-image aliases.
+-- Antigravity now supports gemini-3.1-flash-image as the latest image generation model,
+-- replacing the previous gemini-3-pro-image.
 --
 -- Strategy:
--- Incrementally upsert only image-related keys in credentials.model_mapping:
--- 1) add canonical 3.1 image keys
--- 2) keep legacy 3-pro-image keys but remap them to 3.1 image for compatibility
--- This preserves user custom mappings and avoids full mapping overwrite.
+-- Directly overwrite the entire model_mapping with updated mappings
+-- This ensures consistency with DefaultAntigravityModelMapping in constants.go
