Summary of changes:
node.tsx- Refactored to make live span behavior deterministic and accurate, especially around completion detection, duration correctness, and smooth live rendering.isLive->traceIsLive) instead of inferring fromroot.endTime.getTerminalTimestamp(...)so terminal events (*_completed,*_failed, etc.) stop spans from being treated as live.getHighResInMsand computed a singledurationMsfor display + layout.segmentNode(canonical/live-adjusted node) and used it consistently for layout, events, and rendering.durationMsintoSpanContentso content reflects live/terminal-correct timing.span-content.tsx- Supports externally computed live/terminal-correct duration, so labels and segment timing stay in sync with live span updates.context.tsx- Made changes to ensure zoom/scale behavior stays correct when panel visibility, panel width, or selection changes, avoiding stale scale math.trace-viewer.tsxuse-streaming-spans.ts- Fixed a race condition where outdated worker results were being used, preventing old row calculations from overwriting newer state.workflow-trace-view.tsx- Made fixes to keep context-menu behavior and selected-span events reliably in sync during live updates, while tightening step duration bounds to the run/viewer end time.
