Subject: [PATCH] fix(tracing): show model-call reasoning above the answer, not
 below

The viewer's Model Output card appended the (folded) reasoning block after
the assistant answer, so it read bottom-up. Reasoning precedes the answer
chronologically -- the model thinks, then responds -- so render it at the
top of the card, kept collapsed since it is long and diagnostic.
