FocusOrderConflictAnalyzer
Detects chaotic tabindex patterns across the page (positive values, gaps).
What it detects
Positive `tabindex` values override DOM-order focus and are notoriously fragile across page changes. This analyser examines the global tabindex picture across the DocumentModel and reports patterns that confuse keyboard users — positive values mixed with zero, gaps in the sequence, focus traps that aren't intentional.
