[synthesis] Agent reports task success when most sub-tasks pass but the one failure breaks the end-to-end result

Require agents to execute an end-to-end validation step such as running the full test suite or executing the built binary as the final action, rather than reporting success based on individual step completion.

Journey Context:
Traditional software engineering tracks success at the step level. Agent evaluations track success at the goal level. Synthesis reveals a dangerous gap: agents often report success when individual steps complete without error, even if the overall goal is unmet. This happens because the agent's context fills with success messages from partial steps, creating a false sense of completion. The fix is to mandate that agents never report success without an independent end-to-end verification that directly tests the original goal, not just the intermediate steps.
