fix(google): remove the shut-down veo-3.1-generate-preview registration

CHANGELOG.md

@@ -17,6 +17,7 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - **Images** — OpenAI image edits send `mask` and `reference_images` (up to 16 input images) instead of warning and dropping them; edits use the JSON `images` body, and generation with `reference_images` is served by `/images/edits` (#568).
 - **Images** — OpenAI `gpt-image-2`, `gpt-image-2.5-flare` and `gpt-image-2.5-sunburst` accept any documented `WIDTHxHEIGHT` size (multiples of 16, 1:3 to 3:1, at most 3840 per edge, 655,360–8,294,400 pixels) with the standard sizes kept as presets, instead of eight fixed sizes (#564).
 - **Text** — Anthropic on Claude on Google Cloud (GoogleADC) sends image and document inputs as base64 sources; the route accepts no URL sources (#570).
+- **Videos** — Google `veo-3.1-generate-preview` is no longer registered: the Gemini API shut it down on October 22, 2026 and now answers 404 `NOT_FOUND`. No Veo model remains registered; Google's replacement is `gemini-omni-1.2-flash` (#585).
