Trade Picker

Fixed:

• Cured villagers keep the trades you picked. Curing a zombie villager replaces it with a new entity behind the scenes, which detached it from your picks. The villager came back selling trades you never chose, and the picker never opened for it again. Your picks and your claim now follow a villager through the whole zombify-and-cure round trip.
• Reputation discounts actually reach the trade screen. Discounts from curing a villager, and from Hero of the Village, were being applied and then wiped a moment before the screen opened, so you saw the full price every time. They now show correctly on every open.
• Villagers keep their picks through a Nether portal. (#12) Profiles were stored per dimension, so a villager carried through a portal read as unclaimed on the far side and could be re-picked or reset by anyone. Profiles are now stored once for the whole world, and profiles saved by older versions are folded into the shared store automatically.
• Trade use-counts no longer roll back after a reload. (#11) Trades a villager already had before you installed the mod could reset their use counts when the world reloaded, restocking them early.
• One unreadable profile no longer takes the rest down with it. (#13) A single malformed entry stopped every villager profile in the world from loading. Bad entries are now skipped one at a time.
• Cost scaling applies to tipped-arrow trades. (#17) The fletcher's tipped-arrow trades ignored the cost-scaling setting.
