Harness Runtime adds OpenHands agent support

DigitalOcean Harness Runtime now supports OpenHands agents.

Simulation is now available in public preview.

Inference Router has been redesigned as a single managed router. Send requests to the inference-router model name, optionally with a routing_preference of balanced, budget, or quality, and the router selects the best model for each request.

DigitalOcean Signals is now available in public preview for Harness Runtime agents and Serverless Inference.

Preset routers and the Create Router flow have been removed from the Control Panel. Existing custom routers and preset router slugs continue to serve requests.
