- Define EquipmentSet type + computeSetBonuses utility in packages/types
- Add setId field to Equipment type and assign sets to 27 equipment items
- Create 9 named equipment sets (Iron Vanguard → Eternal Throne) with 2pc/3pc bonuses
- Apply set combat multiplier in boss route
- Apply set gold/click multipliers in tick engine and click handler
- Include set bonuses in anti-cheat delta validation
- Show active set bonus strip + set badge per card in EquipmentPanel
