feat(openrouter/openai/gpt-5.6-terra-pro): add new models [bot]

[models-bot]

Auto-generated by model-addition-agent for openrouter/openai/gpt-5.6-terra-pro.

---

Note

Low Risk
Metadata-only addition with no runtime or application logic changes; incorrect pricing or limits would only affect routing/cost display until corrected.

Overview
Registers OpenRouter model openai/gpt-5.6-terra-pro via a new provider YAML (auto-generated by the model-addition agent).

The entry defines chat mode, serverless provisioning, token pricing (including prompt-cache read/create), a ~1.05M context window, 128k max output, multimodal inputs (text, image, PDF), tool/function-calling features, and thinking support, with source link to OpenRouter.
