StillHammer 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
