VillagerTradeFix — Full port for Minecraft 1.20.1 (Forge)

Fixes villager trade abuse.

Villagers remember their trades per job site (cycling job sites no longer resets trade offers) and reputation discounts are capped. This is a full port for Minecraft 1.20.1 (Forge) of VillagerTradeFix by Globox1997: the original prepareOffersFor logic (Mojang updateSpecialPrices) and NBT trade memory work in full on this version.

Port notes (1.20.1 Forge)

• Java 17 · Forge 47.4.20 · Official Mojang mappings · Mixin
• Config replaced with a simple JSON file (config/villagertradefix.json): baseVillagerOfTheHeroDiscount, extraVillagerOfTheHeroDiscount, maxReputationDiscount, maxReputation
• Trade memory stored as MerchantOffers NBT (Recipes tag) per job, keyed by profession name (persisted across restarts)
• The optional Numismatic Overhaul compat mixin is not included (dependency unavailable on this branch)
• Built and verified in CI via GitHub Actions, including a headless runtime test that launches the client, joins a world, and quits cleanly
