Fix HTML dashboard delta arrows: compute in chronological order
The detail table displays entries newest-first (array_reverse), but delta indicators were computed during the reversed loop — comparing each entry to its visual predecessor (which is chronologically newer). This made improving SCI scores appear as ▲ worse. Fix: pre-compute deltas in chronological order before reversing the array for display. Each entry's delta now correctly compares to its chronological predecessor. Before: iter3(0.11) showed ▲ worse (comparing to iter2 above it) After: iter3(0.11) shows ▼ better (comparing to iter2 before it) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
