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.

10a9ac76c3 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.

4a30b1f149 feat(BgfxRenderer): Complete Phase 4 - ShaderManager integration 
- Refactor ShaderManager to use RHI abstraction (no bgfx:: exposed)
- Implement Option E: inject ShaderHandle via pass constructors
- SpritePass/DebugPass now receive shader in constructor
- RenderPass::execute() takes IRHIDevice& for dynamic buffer updates
- SpritePass::execute() updates instance buffer from FramePacket
- Integrate ShaderManager lifecycle in BgfxRendererModule
- Add test_22_bgfx_sprites.cpp (visual test with SDL2)
- Add test_22_bgfx_sprites_headless.cpp (headless data structure test)
- Update PLAN_BGFX_RENDERER.md with Phase 4 completion and Phase 6.5

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

b065463226 fix(BgfxRenderer): Implement CommandBuffer execution and topological sort 
- Add executeCommandBuffer() to IRHIDevice interface
- Implement full command buffer execution in BgfxDevice (175 lines)
  - Handles SetState, SetTexture, SetUniform, SetScissor
  - Handles SetVertexBuffer, SetIndexBuffer, SetInstanceBuffer
  - Handles Draw, DrawIndexed, DrawInstanced, Submit
- Rewrite RenderGraph::compile() with Kahn's algorithm for topological sort
  - Now respects pass dependencies correctly
  - Uses sortOrder as secondary key via priority queue
  - Detects cycles and throws exception
- Call device.executeCommandBuffer() in RenderGraph::execute()
- Make OpenSSL optional with std::hash fallback for SHA256
