v0.4.0 — Fable 5 on the balanced route
Added Anthropic Fable 5 to the balanced route and cut cold-start latency.
We added Fable 5 to the bitrouter-balanced route. Routine calls keep going to
open models; Fable 5 now handles the harder calls that earn frontier pricing.
- Faster cold starts on first request after idle.
- No harness changes required.
