262eef377e feat(BgfxRenderer): Phase 5.5 - Sprite shader with instancing and texture support
- 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.

1443c1209e feat(BgfxRenderer): Complete Phase 2-3 with shaders and triangle rendering
Phase 2 - RHI Layer:
- Fix Command struct default constructor for union with non-trivial types
- Add missing mutex includes in ResourceCache.cpp
- Fix const_cast for getChildReadOnly in SceneCollector

Phase 3 - Shaders & Visual Test:
- Add ShaderManager for centralized shader loading
- Embed pre-compiled shaders (OpenGL, Vulkan, DX11, Metal)
- Add test_20_bgfx_rhi: 23 unit tests for RHI components
- Add test_21_bgfx_triangle: visual test rendering colored triangle

Test results:
- RHI unit tests: 23/23 passing
- Visual test: ~567 FPS with Vulkan renderer
