On in staging only. Re-run after prod rollout.

• Eng PR: trunk2#4098
• Flag: enableFlakyTestsDetectionHistorySwimlane
• Flag state: prod ON but fallthrough=false (only trunk.io impersonators); test fallthrough=true (all users)
• Signals:
  • trunk2#4098 merged 2026-06-08
  • LD prod: flag enabled but default variation is OFF (fallthrough variation 1 = false); only users with impersonatorEmail ending in @trunk.io receive true
