/**
 * EntityTextureResolver
 *
 * Shared utilities for resolving entity textures from various sources:
 * - Project items (custom content)
 * - Vanilla resources (Database/VanillaProjectManager)
 * - Direct file paths
 * - URLs
 *
 * This centralizes texture resolution logic that was previously duplicated
 * across ModelViewer, MobViewer, CLI rendering, and MCP server.
 *
 * TEXTURE RESOLUTION ORDER:
 * -------------------------
 * 1. Explicit texture data (Uint8Array) if provided
 * 2. Project item lookup (for custom content)
 * 3. Entity resource definition (client_entity -> textures map)
 * 4. Vanilla resources (built-in Minecraft textures)
 * 5. Fallback path construction
 *
 * TEXTURE PATH FORMATS:
 * ---------------------
 * Minecraft uses several path formats:
 * - "textures/entity/pig/pig" (resource pack relative, no extension)
 * - "textures/entity/pig/pig.png" (with extension)
 * - Full paths for custom content
 *
 * Last Updated: December 2025
