- Integration with [gogpu ecosystem](https://github.com/gogpu) via gputypes
- Full webgpu.h spec compliance for enum values
- Comprehensive conversion layer (`wgpu/convert.go`) for wgpu-native v27 compatibility
- TextureFormat (~45 formats), VertexFormat (~30 formats)
- VertexStepMode, TextureSampleType, TextureViewDimension, StorageTextureAccess
- Wire structs with correct FFI padding (uint64 flags)

### Fixed

- TextureFormat enum values mismatch (BGRA8Unorm was 0x17, now correct 0x1B)
- Compatibility with gogpu Rust backend
- Struct padding in BindGroupLayout wire structs (sampler, texture, storage)
- PipelineLayout creation in examples (use CreatePipelineLayoutSimple)
- GetModuleHandleW: kernel32.dll instead of user32.dll (all Windows examples)
- Sampler MaxAnisotropy default (wgpu-native requires >= 1)
- Texture SampleCount/MipLevelCount defaults (wgpu-native requires >= 1)
- render_bundle shader: fallback without primitive_index (works on all GPUs)
