This commit fixes several issues that caused the Windows cross-compilation build (`scripts/build_win.sh`) to fail.
The root causes were platform-specific API differences in the wgpu-native library and incorrect dependency tracking in the CMake build system for generated code.
Changes:
- **`tools/seq_compiler.py`**: The timeline generator now wraps `depthSlice` assignments in `#if !defined(DEMO_CROSS_COMPILE_WIN32)` directives to handle API differences in `WGPURenderPassColorAttachment`.
- **`src/gpu/gpu.h`**: The `gpu_init_color_attachment` helper is now platform-aware, using a preprocessor guard for the `depthSlice` member.
- **`src/effects/*.cc`**: All effects are updated to use the new platform-aware helper or have explicit guards for `depthSlice`. Also, replaced `WGPUTexelCopyTextureInfo` with the cross-platform alias `GpuTextureCopyInfo` in `rotating_cube_effect.cc`.
- **`cmake`**: Added `tools/seq_compiler.py` as an explicit dependency to the `generate_timeline` and `generate_test_demo_timeline` custom commands. This ensures that changes to the generator script correctly trigger a rebuild of the generated C++ files.
- **`scripts/build_win.sh`**: Removed the erroneous attempt to build the `seq_compiler.py` script as a native executable.
With these changes, the Windows cross-compilation build now completes successfully.

- 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.

Add -j8 flag to all cmake --build commands to use 8 threads for
faster parallel compilation across gen_assets.sh, crunch_demo.sh,
and build_win.sh scripts.

- Replaced invalid 'i++' with 'i = i + 1' in the shader's calc_shadow function loop.
- This resolves the shader parsing error and allows the 3D renderer test to run successfully on all platforms.

Fixes seq_compiler build for Windows cross-compilation. Moves common WebGPU compatibility shims to gpu.h. Applies project-wide coding style via clang-format. Verified on both macOS (native) and Windows (cross-compile).
