Pull request overview

This PR updates the generated SDK types and wire tests to reflect new Agents API fields for expert configuration and schema support, and adjusts the integration test script entrypoint.

Changes:

• Added configSchema to registry experts, and added config (create) / resolvedConfig (response) to expert references across API + serialization layers.
• Updated wire tests to include the new configSchema field in getRegistryExperts expectations.
• Simplified test:integration to run via vitest --config vitest.integration.config.mts and bumped Fern CLI metadata.
