Trade Picker

Fixes non-librarian issues: enchanted gear (weapons, armor, tools, bows, rods) and tipped arrows now expand into choosable cards in the picker, instead of letting vanilla roll them.

What's new

• Weaponsmith / Armorer / Toolsmith / Fletcher / Fisherman --- pick the enchantment on the item they sell.
• Fletcher tipped arrows --- pick the potion (e.g. Arrow of Weakness).
• Two modes: Headline (default --- pick the main enchantment; the game still rolls its level and any bonus enchantments) or Single (pick the exact enchantment and level). Switchable in ModMenu (Fabric) or config/tradeoptimizer.json.
• Optional per-profession cost scaling --- make rarer/higher enchantments cost more emeralds; off by default.
• Everything stays within what that villager could roll in vanilla --- no enchantments or levels it couldn't normally offer.

Notes

• Fabric + NeoForge, Minecraft 26.2. Worlds carry over between loaders.
• No new items, blocks, or recipes.
