Report #37064

[synthesis] Partial success in parallel tool calls masks total failure of the overall objective

Implement strict dependency graph validation where downstream nodes check the semantic success of upstream nodes, not just their HTTP status code or return code.

Journey Context:
In agentic workflows, if a node returns a 200 OK or valid JSON, the graph proceeds. However, a tool can successfully execute the wrong action \(e.g., querying the wrong database\). The graph marks the step as success, and the final aggregator lacks the context to realize the overall goal failed. The journey involves moving from syntactic success \(no errors\) to semantic success \(achieved intended outcome\).
