Report #36594

[synthesis] Agent interprets HTTP 200 or exit code 0 with empty/degraded payload as successful completion

Implement 'semantic success' validators that check for non-empty, meaningful results; treat 'successful' empty responses as failures requiring retry or alternate path

Journey Context:
Standard error handling catches exceptions, but business logic failures that return 200 with \{'status': 'not\_found'\} are missed. The synthesis is semantic validation layer beyond HTTP status, because partial success \(technical success \+ business failure\) masks total failure and triggers premature task completion.
