feat(xai): add new models [bot]

[harshiv-26]

Auto-generated by model-addition-agent for provider xai.

---

Note

Low Risk
Adds two new xai model config YAMLs with pricing and modality metadata; no runtime logic changes, so risk is limited to potential misconfiguration of costs/model IDs.

Overview
Adds two new xai provider model definitions, grok-4.3 and grok-4.3-latest, including token/image pricing, cache read token cost, supported text+image input with text output, and chat mode.

New model configs missing critical fields present in siblings

High Severity

Both grok-4.3.yaml and grok-4.3-latest.yaml are missing several fields that every other grok-4 family model defines: features (e.g. function_calling, structured_output, prompt_caching), limits.context_window (should be 1000000 per xAI docs), thinking: true, removeParams: [reasoning_effort], provisioning, status, and supportedModes. Without these, the model won't advertise function calling or structured output support, won't report its context window, and won't be flagged as a reasoning model — all of which are confirmed capabilities of grok-4.3.
