WorldSeedEntityEngine v12.0.0

WorldSeedEntityEngine v12 updates the engine to Minecraft 26.2 and the corresponding Minestom release.

Highlights:

• Restores player emotes on Minecraft 26.2, including the updated shader interface and centered player-part geometry.
• Corrects animation translations, interpolation, blending, discontinuous keyframes, and transform propagation.
• Adds ModelEntity, locators, bone visibility, animation effects, and modern nametags.
• Fixes resource-path sanitization and texture decoding problems reported in #36 and #65.
• Updates the demo resource pack to format 88 and SHA-1 pack hashes.

Breaking changes:

• Legacy model damage and interaction events are removed. Use standard Minestom entity events through the model owner.

Validated with the full Gradle test/build/Javadoc suite and an automated Fabric 26.2 client loading and rendering the generated resource pack.
