OpenHands Integrates SDK AgentSettings Schema, Enabling Dynamic GUI Updates

OpenHands has integrated the SDK's `AgentSettings` schema directly into its GUI and backend, fundamentally changing how user-facing settings are managed. The frontend now dynamically fetches and renders settings pages from a new `/api/settings/schema` endpoint served by the SDK, eliminating the previous hard-coded field definitions. This architectural shift means updates to the underlying agent settings in the SDK are now immediately and automatically exposed to end-users through the interface without requiring separate frontend code changes.

The integration ensures these dynamically loaded settings are fully plumbed through the application stack, directly linking them to new conversation start requests. This creates a closed loop where configuration changes made in the GUI directly influence agent behavior at runtime. The change, which also touches legacy v0 code for consistency, addresses upstream SDK issue #2228 and resolves OpenHands issue #13788, marking a significant step in unifying the platform's configuration layer.

This move reduces frontend maintenance burden and tightens the coupling between the SDK's capabilities and the user interface, potentially accelerating the rollout of new agent features and parameters. It signals a maturation of OpenHands's architecture, prioritizing dynamic, schema-driven interfaces over static, manually synchronized code—a critical evolution for platforms relying on rapidly evolving AI agent backends.
