feat(BgfxRenderer): Phase 5 - Visual sprite test with IIO pipeline
- Add test_23_bgfx_sprites_visual.cpp: full visual test with SDL2 + IIO - Fix IRHIDevice::init() to accept nativeDisplayHandle for X11/Linux - Fix BgfxDevice::createBuffer() with proper VertexLayout for dynamic buffers - Use double for native handle config values (preserves 64-bit pointers) - Add debug logging in BgfxRendererModule initialization Pipeline verified working: - Module loads and initializes with Vulkan - IIO messages routed correctly (sprites, camera, clear) - SceneCollector collects and builds FramePacket - RenderGraph executes passes - ~500 FPS throughput Note: Sprites not visually rendered yet (shader needs instancing support) This will be addressed in a future phase. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
