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.

- create:clipboard_type (clipboard type)
Illegal Component Handling:
- Generates clean clipboard instance
- Migrates whitelisted valid data
- Auto-replaces dropped item
Exploit Prevention: Blocks item duplication via container or other illegal components
