* feat: integrate models.dev registry for auto-populated model defaults

* fix: fall back to upstream provider for model registry lookup
When the browseros meta-provider is used, the registry lookup now
also tries the upstream provider (e.g., openrouter, anthropic) so
that BrowserOS-hosted models get correct context window and image
support defaults.

* fix: add Object.hasOwn guards to prevent prototype chain lookup
Addresses Greptile review: bracket notation on the registry object
could return prototype-chain properties for keys like __proto__ or
constructor, bypassing the 404 guard in the route handler.
