Summary

  • Align streaming responses with the official LangGraph Server protocol (messages/metadata, messages/partial,

  • Return real graph topology and schemas from assistant graph/schemas endpoints
  • Add CORS middleware and ContentType-fix middleware (fixes Studio 422 errors)
  • Fix assistant/search 422 and CI issues

Closes #27
