AR - Cataclysm: Spellbooks

Fixes NoClassDefFoundError: CoreGeoBone crash caused by AzureLib 3.1.0+ removing the class.

Cataclysm: Spellbooks is a magic addon for the Cataclysm mod, adding new spells, summoned creatures, and magical mechanics to Minecraft 1.19.2.

What was fixed:
- Resolved NoClassDefFoundError: mod/azure/azurelib/core/animatable/model/CoreGeoBone crash on startup
- The CoreGeoBone class was removed in AzureLib 3.1.0, but Cataclysm: Spellbooks armor renderers still referenced it directly, causing the game to crash at launch when using AzureLib 3.1.0 or newer
- All affected armor renderer classes have been updated to use the correct AzureLib 3.1.0+ API
- Removed @AutoSpellConfig annotation from SummonedAmethystCrab which caused a secondary initialization error

This build was compiled for use in the Akashic Records of Tensura modpack. No gameplay changes were made — only compatibility issues were resolved.

Requires AzureLib 3.1.0+ and the base Cataclysm mod for 1.19.2.
