Implement client-side WebGPU API with command buffer recording

[Copilot]

• Analyze existing WebGL client-side architecture and command buffer patterns
• Create WebGPU context interface following WebGL patterns
• Implement WebGPU adapter and device for client-side command recording
• Create WebGPU command encoder and command buffer recording
• Add WebGPU render pass encoder for draw commands
• Update client graphics namespace to include WebGPU classes
• Add basic unit tests for WebGPU interface instantiation
• Ensure code follows JSAR Runtime's style and quality standards
• Validate implementation with linting and formatting checks
• Split WebGPU classes into individual files

✅ Implementation Complete and File Structure Optimized

Successfully split the WebGPU implementation into individual files following the established WebGL pattern, where each class corresponds to a single file:

File Structure After Split:

• webgpu_context_attributes.hpp - Context configuration attributes (23 lines)
• webgpu_adapter.hpp/.cpp - WebGPU adapter interface (52 lines)
• webgpu_device.hpp/.cpp - WebGPU device interface (72 lines)
• webgpu_queue.hpp/.cpp - WebGPU queue interface (37 lines)
• webgpu_context.hpp/.cpp - Main WebGPU context (51 lines)
• webgpu_command_buffer.hpp/.cpp - Command buffer container (66 lines)
• webgpu_command_encoder.hpp/.cpp - Command recording (109 lines)
• webgpu_render_pass_encoder.hpp/.cpp - Render pass commands (71 lines)
• webgpu_buffer.hpp - Buffer resource placeholder (33 lines)
• webgpu_texture.hpp - Texture resource placeholder (33 lines)
• webgpu_bind_group.hpp - Bind group placeholder (33 lines)
• webgpu_render_pipeline.hpp - Render pipeline placeholder (33 lines)
• webgpu_compute_pipeline.hpp - Compute pipeline placeholder (33 lines)

Improvements Made:

• One Class Per File: Each WebGPU class now has its own header/source file pair
• Consistent with WebGL Pattern: File sizes and structure match existing WebGL files
• Proper Dependencies: Headers only include necessary dependencies
• Clean Architecture: Forward declarations minimize coupling between classes
• Easy Maintenance: Individual files are easier to modify and understand

Quality Validation:

• ✅ All C++ code formatted with clang-format (911 files processed)
• ✅ Headers compile successfully with correct include dependencies
• ✅ File structure follows established WebGL conventions
• ✅ Updated class declarations in client/classes.hpp
• ✅ Test files updated to use new header structure

This addresses the feedback to split WebGPU files so each corresponds to a single class, making the codebase more maintainable and consistent with the existing WebGL implementation patterns.

Fixes #347.

@copilot Please split these WebGPU files, ensuring that each file corresponds to a single class.

Done! I've split all WebGPU classes into individual files following the established WebGL pattern. Each class now has its own header/source file pair:

13 new files created:

• webgpu_context_attributes.hpp - Context configuration
• webgpu_adapter.hpp/.cpp - Adapter interface
• webgpu_device.hpp/.cpp - Device interface
• webgpu_queue.hpp/.cpp - Queue interface
• webgpu_context.hpp/.cpp - Main context (updated)
• webgpu_command_buffer.hpp/.cpp - Command buffer
• webgpu_command_encoder.hpp/.cpp - Command encoder (updated)
• webgpu_render_pass_encoder.hpp/.cpp - Render pass encoder
• webgpu_buffer.hpp, webgpu_texture.hpp, webgpu_bind_group.hpp - Resource placeholders
• webgpu_render_pipeline.hpp, webgpu_compute_pipeline.hpp - Pipeline placeholders

The file structure now matches the WebGL pattern where each file contains a single class, making the codebase more maintainable and easier to navigate.
