feat: Implement returns_result and improve HTTP plugin stability
- Add returns_result=true configuration for HTTP server methods - Fix ResultBox downcasting in interpreter calls - Improve HTTP plugin with server_id tracking and response ID hints - Add TCP connection support with fallback to stub mode - Implement response ID mapping improvements - Fix various race conditions in concurrent request handling This partially addresses the HTTP response body empty issue, though ID mapping still needs further refinement.
