Distant Horizons LOD & Terrain Improvements

• New “Distant Horizons Render Mode” option in world customization: Fast (Approximate) or Detailed (Slow).
• Fast DH LOD generator with improved performance, lighting, and terrain layering.
• Tree canopy approximation for distant forests (clustered crowns, trunk hints, leaf lift) with tuned density (WIP).
• Initial underwater vegetation approximation (seagrass/kelp mix) for oceans and rivers in Fast DH mode (not visible in‑game yet).
• Detailed DH mode now uses chunk-based generation so trees and structures appear in distant LODs.
• Fixed terrain elevation seams/cross‑line artifacts by blending elevation samples across tile boundaries.
• Amethyst geodes disabled by default and locked in settings to prevent underground generation.

Notes

• The Fast DH generator is work in progress and will continue to receive visual improvements and tuning. Trees in some areas may look off, and there may be some performance issues, crashes, or visual bugs.
