feat(openrouter): update model YAMLs [bot]

[models-bot]

Auto-generated by poc-agent for provider openrouter.

---

Note

Low Risk
Config-only metadata additions to model YAMLs with no behavioral logic changes; risk is limited to consumers that strictly validate YAML schema.

Overview
Adds additional metadata to three OpenRouter model definition YAMLs (ibm-granite/granite-4.1-8b, openrouter/owl-alpha, x-ai/grok-4.3): provisioning: serverless, a sources URL, status: active, and explicit supportedModes: [chat].

No pricing/limits/features change; this is a config/schema augmentation to make model availability and provenance explicit.
