Changed from lightmapTexture with lighting enabled to emissiveTexture with lighting disabled for better performance. The new approach provides the same lighting illusion without expensive per-pixel lighting calculations.
- Added LightmapGenerator.ENABLED toggle for performance testing
- Updated buildColor.ts to use emissiveColor + emissiveTexture with disableLighting = true
- Updated buildMissingMaterial() to match new rendering approach
- Fixed buildTool.ts to access emissiveColor instead of diffuseColor for material color detection
