Sky Shadow Fix removes ugly fake shadows caused by high floating islands or floating terrain.

Minecraft normally treats large floating terrain as sky-blocking, which can create huge dark blobs on the ground below. This mod detects those high-altitude shadow zones and fixes their gameplay impact by preventing hostile natural spawns there.

Features:
- Fixes fake shadow zones under high floating terrain
- Prevents hostile natural mob spawns in those fake shadows
- Keeps normal cave, forest, building, and terrain shadows untouched
- Conservative detection by default
- Server-side spawn fix
- Optional client-side visual fix if supported

Default behavior:
Only shadows caused by overhead terrain above Y=100 and at least 67 blocks above the ground are treated as floating shadows.

This mod does not change world generation and does not place hidden light blocks.
