Created automated test suite for texture_manager.cc with 7 test cases:
- Basic initialization and shutdown
- Create texture from raw RGBA8 data
- Create procedural texture (using gen_noise)
- Get texture view for non-existent texture (nullptr test)
- Create and retrieve multiple textures
- Procedural generation failure handling
- Shutdown cleanup verification
Replaced old compilation-only test with proper automated test using
WebGPUTestFixture for headless GPU testing. Registered with CTest as
test #27 (TextureManagerTest).
Coverage Impact:
- Before: texture_manager.cc had 0% coverage (not run by CTest)
- After: 100% coverage (64/64 lines, 5/5 functions)
All 27 tests pass.

Reorganized platform windowing code into dedicated subdirectory for
better organization and consistency with other subsystems (audio/, gpu/, 3d/).
Changes:
- Created src/platform/ directory
- Moved src/platform.{h,cc} → src/platform/platform.{h,cc}
- Updated 11 include paths: "platform.h" → "platform/platform.h"
- src/main.cc, src/test_demo.cc
- src/gpu/gpu.{h,cc}
- src/platform/platform.cc (self-include)
- 6 test files
- Updated CMakeLists.txt PLATFORM_SOURCES variable
Verification:
✓ All targets build successfully (demo64k, test_demo, test_platform)
✓ test_platform passes (70% coverage maintained)
✓ demo64k smoke test passed
This completes the platform code reorganization side quest.
No functional changes, purely organizational.

- Consolidated all WebGPU shims and platform-specific logic into src/platform.h.
- Refactored platform_init to return PlatformState by value and platform_poll to automatically refresh time and aspect_ratio.
- Removed STL dependencies (std::map, std::vector, std::string) from AssetManager and Procedural subsystems.
- Fixed Windows cross-compilation by adjusting include paths and linker flags in CMakeLists.txt and updating build_win.sh.
- Removed redundant direct inclusions of GLFW/glfw3.h and WebGPU headers across the project.
- Applied clang-format and updated documentation.
handoff(Gemini): Completed Task #20 and 20.1. Platform abstraction is now unified, and core paths are STL-free. Windows build is stable.

- Replaced white noise with smooth value-like noise.
- Implemented periodic texture generation (seam blending).
- Integrated bump mapping into Renderer3D using finite difference of displaced SDF.
- Updated test_3d_render with noise texture and multiple SDF shapes (Box, Sphere, Torus).

|
- Extended mini_math.h with mat4 multiplication and affine transforms.
- Implemented TextureManager for runtime procedural texture generation and GPU upload.
- Added 3D system components: Camera, Object, Scene, and Renderer3D.
- Created test_3d_render mini-demo for interactive 3D verification.
- Fixed WebGPU validation errors regarding depthSlice and unimplemented WaitAny.
