[synthesis] Interleaved causality confusion in tool-reasoning loops

Assign explicit correlation IDs to each tool call; map observations back to specific call IDs in reasoning trace.

Journey Context:
When agents interleave tool calls with reasoning \(call tool A, think, call tool B, think, see result from A\), they lose track of which observation belongs to which tool call. This leads to phantom causality: attributing the result of tool A to tool B, or thinking tool B produced output when it was actually tool A. In distributed systems, this is solved with trace context \(span IDs\), but agent frameworks often omit this. The fix is to treat tool calls as distributed transactions with explicit correlation IDs, not just ordered lists.
