The bead description claimed significant implementation gaps, but upon
investigation all mentioned features were already complete:
- memoryProfiler.ts: exists (f824c2e)
- FileHeatmap treemap/timelapse: fully implemented
- SpanDag zoom/pan: fully implemented
- Only 1 test failing (selector bug, now fixed)
All tests pass: 2399 passed, 4 skipped (65 test files)
