- 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 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
