Create Bugfix: Clipboard Patch

Introduction
This mod fixes a critical exploit in Create Mod's clipboard item for Minecraft 1.21+. Maliciously modified clipboards with illegal data components could trigger item duplication. The patch automatically sanitizes component data to ensure gameplay security.

Technical Mechanism

1. Event Monitoring: Hooks into ItemTossEvent (player item-drop event)
2. Item Identification: Detects if dropped item is create:clipboard
3. Component Whitelisting: Only preserves:
   • create:clipboard_pages (page content)
   • create:clipboard_type (clipboard type)
4. Illegal Component Handling:
   • Generates clean clipboard instance
   • Migrates whitelisted valid data
   • Auto-replaces dropped item
5. Exploit Prevention: Blocks item duplication via container or other illegal components

Fix Impact

• Permanently patches item duplication exploits
• Maintains normal clipboard functionality (text/icons preserved)
• Compatible with Create Mod versions larger than 6.0
