Phase 3 - Mermaid Highlighting:
- Add highlightedNodeId prop to DebugMermaidDiagram for trace hover highlighting
- Cyan dashed border distinguishes trace hover from walker progress (amber)
Phase 4 - Problem Trace Component:
- Create ProblemTrace.tsx displaying step-by-step computation trace
- Shows node title, transforms applied, working problem evolution
- Timeline UI with expand/collapse for each step
- Integrate into WorksheetDebugPanel expanded details
Phase 5 - Unified Answer Computation:
- Update WorksheetDebugPanel to use simulateWalk + extractAnswer
- Update worksheet-generator.ts to use unified computation path
- Update test-case-validator.ts runTestCaseWithFlowchart to use simulateWalk
- All places with full ExecutableFlowchart now use single code path
