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.

e004bc015b feat: Windows portage + Phase 4 SceneCollector integration 
- Port to Windows (MinGW/Ninja):
  - ModuleFactory/ModuleLoader: LoadLibrary/GetProcAddress
  - SystemUtils: Windows process memory APIs
  - FileWatcher: st_mtime instead of st_mtim
  - IIO.h: add missing #include <cstdint>
  - Tests (09, 10, 11): grove_dlopen/dlsym wrappers

- Phase 4 - SceneCollector & IIO:
  - Implement view/proj matrix calculation in parseCamera()
  - Add IIO routing test with game→renderer pattern
  - test_22_bgfx_sprites_headless: 5 tests, 23 assertions pass

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

d63d8d83fa feat: Add BgfxRenderer module skeleton 
- Add complete BgfxRenderer module structure (24 files)
- RHI abstraction layer (no bgfx:: exposed outside BgfxDevice.cpp)
- Frame system with lock-free allocator
- RenderGraph with ClearPass, SpritePass, DebugPass
- SceneCollector for IIO message parsing (render:* topics)
- ResourceCache with thread-safe texture/shader caching
- Full IModule integration (config via IDataNode, comm via IIO)
- CMake with FetchContent for bgfx
- Windows build script (build_renderer.bat)
- Documentation (README.md, USER_GUIDE.md, PLAN_BGFX_RENDERER.md)
- Updated .gitignore for Windows builds
