feat: Implement returns_result and improve HTTP plugin stability

Browse Source 
- 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.
