Traces now support Tree and Waterfall views

Traces in Vercel Logs now offer Tree and Waterfall visualization modes to help you understand span hierarchy, critical path, and timing. Tree view groups spans by parent-child relationships sorted by duration, while Waterfall view shows all spans on a chronological axis to reveal parallel execution and time bottlenecks.

The Waterfall view places every span on one chronological axis, showing what ran in parallel and where time was lost.
