CuriosPaper v1.1.1 — Advanced Recipe System & API Expansion

This update expands CuriosPaper beyond basic crafting by introducing full vanilla recipe support, safer item upgrades, and tighter server control over in-game editors.

---

🚀 Major Features

Expanded Recipe System

CuriosPaper now supports non-crafting recipe mechanics, enabling real progression and upgrade systems.

New supported recipe types:

• FURNACE — Smelting with configurable time & XP
• BLAST_FURNACE — Fast smelting
• SMOKER — Food cooking
• ANVIL — Item combination & upgrade recipes with XP cost
• SMITHING — Base / addition / template based upgrades

This unlocks:

• Tiered item upgrades
• Anvil-based enhancements
• Smithing-table item evolution
• Smelting-based custom materials

---

NEW: CuriosRecipeTransferEvent

A new cancelable event fired whenever CuriosPaper transfers custom item data during any recipe operation.

Purpose: Vanilla recipes normally discard custom metadata. This event gives addons full control over how data moves from source → result.

Key points:

• Fires for ALL recipe types
• Provides source and result ItemStack
• Allows safe upgrades (e.g. backpack tiers)
• Can cancel crafting if transfer fails
