- Fix JsonDataNode::getChildReadOnly() to handle JSON array access by numeric index
- Fix test_ui_showcase to use JSON array for children (matching test_single_button pattern)
- Add visual test files: test_single_button, test_ui_showcase, test_sprite_debug
- Clean up debug logging from SpritePass, SceneCollector, UIButton, BgfxDevice
The root cause was that UITree couldn't access array children in JSON layouts.
UIButton hover/click now works correctly in both test files.

Phase 7 - Text Rendering:
- Add BitmapFont with embedded 8x8 CP437 font (ASCII 32-126)
- Add TextPass for instanced glyph rendering
- Fix SceneCollector::parseText() to copy strings to FrameAllocator
Phase 8A - Multi-texture Support:
- Add numeric texture ID system in ResourceCache
- SpritePass sorts by textureId and batches per texture
- Flush batch on texture change for efficient rendering
Phase 8B - Tilemap Rendering:
- Add TilemapPass for grid-based tile rendering
- Support tileData as comma-separated string
- Tiles rendered as instanced quads
Window Resize:
- Handle window resize via process() input
- Call bgfx::reset() on size change

- Create proper sprite shader (vs_sprite.sc, fs_sprite.sc) with GPU instancing
- SpriteInstance struct now 80 bytes (5 x vec4) for GPU layout compatibility
- Add BufferDesc::Layout enum (Raw, PosColor, InstanceData) for proper vertex layouts
- BgfxDevice creates correct VertexLayout based on buffer type
- SpritePass uses PosColor layout for quad vertices (Position + Color0)
- Instance buffer uses 5 x vec4 layout (TexCoord7-3) for i_data0-4
- Add texture support with v_texcoord0 interpolation from instance UVs
- Create default white 1x1 texture fallback
- Compile shaders for SPIRV (Vulkan), GLSL (OpenGL), and Metal
Visual test confirms sprites render correctly at ~545 FPS.
