Energy Scythe literal sprite Blockbench models

These are actual .bbmodel files traced directly from your 4 uploaded scythe sprites.

What this pass does:
- uses your real scythe sprite silhouette instead of trying to reinterpret it as a ring/crescent
- converts the visible sprite into merged voxel/cuboid geometry
- preserves the stage 1-4 differences
- uses a shared embedded palette texture in the .bbmodel files

If one of these looks right, the next step is to use that exact silhouette as the in-game model baseline.
