Report #41376

[synthesis] Agent reports task success but critical sub-tasks were silently dropped or skipped

Implement explicit state tracking with boolean completion flags for every required sub-task, and enforce a final validation step that checks all flags before returning 'success' to the user.

Journey Context:
In multi-step agent workflows, a tool might return a 200 OK but perform a no-op \(e.g., updating a record that doesn't exist, or writing an empty file\). The agent sees the success status and proceeds, eventually reporting overall success. Partial success is more dangerous than total failure because it doesn't trigger error handling. Explicit state tracking forces the agent to verify the \*effect\*, not just the \*status\*.
