Provider-agnostic hybrid routing for Genkit — combine on-device and cloud models behind one routing policy.

Changelog

0.1.0

Initial release.

• hybridModel(branches, strategy) — combine N named Genkit Model actions behind one routing policy; returns an ordinary Model.
• hybridModelOnDeviceCloud(onDevice, cloud, strategy) — binary façade with kOnDevice / kCloud keys.
• RoutingStrategy interface returning an ordered list of branch keys (single = pre-routing, multi = fallback, empty = no decision).
• Built-in strategies: PreRoutingStrategy, FallbackStrategy, ConnectivityStrategy, InputSizeStrategy, and combinators FirstMatch, WithFallback.
• Streaming fallback only before the first emitted token.
• Transient-vs-permanent error policy: fallback on availability errors, immediate propagation of permanent ones.
