LightAPI

💡 LightAPI 1.0 - Dynamic Lighting & Volumetric Engine

• Memory Optimization: Fixed excessive startup allocation in SpatialIndex and ConcurrentSparseLong2ObjectMap using lightweight sparse segments.
• GPU Shader Pipeline: Real-time uniform buffer objects (ColorLightUBO) paired with ShaderProgramMixin and WorldRendererMixin for zero-overhead terrain and entity lighting.
• Dynamic Entity Illumination: Injected dynamic photometric querying into EntityRenderer (EntityRendererMixin) so mobs, players, armor stands, and dropped items reflect dynamic lights in real-time.
• Volumetric Emitters: Native spatial support for VOLUME_BOX, SPHERE, CAPSULE, and directional bounds.
• Thread-Safe Snapshotting: Atomic double-buffer baking eliminating render thread stalls.
• Modular SPI Bridge: Clean integration with ColorAPI for multi-channel RGB light propagation.
