refactor: extract specialized render utilities from RenderUtils god class
Break down monolithic RenderUtils.kt (4,786 lines) into focused, specialized classes: Created new utilities: - RenderGL.kt: OpenGL state management (107 lines) * glCapMap management, blend/depth/texture state helpers * setupBlend(), setupRender2D(), restoreRender2D() - RenderPrimitives.kt: 2D shape rendering (226 lines) * Basic shapes: rectangles, circles, gradients, rounded rects * drawRect(), drawCircle(), drawGradientRect(), drawRoundedRect() - Render3D.kt: 3D world rendering (201 lines) * Block boxes, entity bounding boxes, platforms * drawBlockBox(), drawFilledBox(), drawPlatform() - RenderEffects.kt: Visual effects (265 lines) * Shadows, glows, bloom, blur effects with LRU cache * drawShadowRect(), drawBloom(), fakeCircleGlow() - RenderEntity.kt: Entity visual effects (431 lines) * Combat visuals: Crystal, Zavz, Jello, FDP, Lies * drawCrystal(), drawZavz(), drawJello(), drawFDP(), drawLies() - RenderTexture.kt: Texture operations (301 lines) * Modal rects, texture drawing, image-to-texture conversion * drawModalRectWithCustomSizedTexture(), convertImageToTexture() Improvements: - Extracted ~1,500 lines into 6 specialized classes - Added deprecation warnings with ReplaceWith hints - Maintained 100% backward compatibility via delegates - All specialized classes have single responsibility - Proper author attribution (@author Zywl) - Organized imports and removed decorative comments Build: ✅ All tests passing, zero compilation errors
