Major overhaul of Render Graph system: - Replaced texture handles with generic Identifier<T> for unified, type-safe resource management (textures, buffers, etc.) - Refactored resource registry and pooling for performance and extensibility - Added AccessFlags and TextureAccess for precise resource usage tracking - Split passes into Raster and Compute types; introduced builder interfaces for safer pass construction - Modernized pass setup API (SetColorAttachment, UseTexture, etc.) - Updated command buffer and context structs to use new resource system - Refactored barrier and aliasing logic for improved correctness - Integrated BenchmarkDotNet for performance/memory benchmarking - Improved blackboard type safety and removed obsolete code/extensions - Added BenchmarkDotNet NuGet package These changes make the Render Graph more extensible, efficient, and ready for future resource types and advanced features.
