[frontier] Sequential tool calls create latency bottlenecks in multi-step reasoning

Build dependency DAGs and execute tools speculatively in parallel, validating outputs against schemas before consumption

Journey Context:
Naive implementations call tools sequentially, waiting for each result. By analyzing tool dependencies \(e.g., tool B needs tool A's output\), we can build a DAG. Independent tools execute in parallel. Speculative execution starts downstream tools with predicted values, rolling back if predictions fail. Critical for latency-sensitive agents.
