Reroll Plus Plus

Fixed

• Rerolling no longer restocks trades. Previously a reroll reset the usage counters of every offer, so trades you had sold out were unlocked again — rerolling acted as a free restock, bypassing daily restock limits and demand price increases. Now a rerolled offer identical to the previous one (same costs and same result) keeps its uses and demand: locked trades stay locked until a normal vanilla restock, while trades new to the set still start fresh.
• The merchant must be alive at the moment of the reroll — no more paying emeralds for a reroll of a dying merchant.
• Added a 0.5-second server-side cooldown on reroll requests: holding the hotkey or using macros no longer spams reroll sounds and particles visible to everyone nearby.
