Villager Trade Reroll

c leveling breaking after reroll — Villagers now correctly level up after trading when their job block is broken and replaced. Previously, internal XP/level state was left out of sync after rerolling, silently preventing level-ups.

Fixed trades generating empty after reroll — Fresh vanilla trades are now read correctly from a temporary villager after the required server tick, preventing cases where rerolled trades would appear blank.

Fixed exploit: reroll trade persisting after plugin removal — The custom "Reroll Trades" slot is now automatically stripped from all loaded villagers when the plugin is disabled or removed, preventing players from trading a Nether Star for 1 Emerald.
