v0.2.0: gputypes integration

gputypes Integration Release

This release integrates go-webgpu with the gogpu ecosystem through github.com/gogpu/gputypes.

⚠️ Breaking Changes

• All WebGPU types now use github.com/gogpu/gputypes directly
  • Example: wgpu.TextureFormatBGRA8Unorm → gputypes.TextureFormatBGRA8Unorm
  • Enum values now match webgpu.h specification

✨ Added

• Integration with gogpu ecosystem via gputypes
• Full webgpu.h spec compliance for enum values
• Comprehensive conversion layer for wgpu-native v27 compatibility
  • TextureFormat (~45 formats), VertexFormat (~30 formats)
  • Wire structs with correct FFI padding (uint64 flags)

🐛 Fixed

• TextureFormat enum values mismatch (BGRA8Unorm was 0x17, now correct 0x1B)
• Compatibility with gogpu Rust backend
• All 11 examples now work correctly

📦 Dependencies

• goffi v0.3.7 (ARM64 Darwin improvements)
• wgpu-native v27.0.4.0

Migration Guide

// Before (v0.1.x)

format := wgpu.TextureFormatBGRA8Unorm

// After (v0.2.0)
import (
    "github.com/go-webgpu/webgpu/wgpu"
    "github.com/gogpu/gputypes"
)
format := gputypes.TextureFormatBGRA8Unorm
