- Major architectural refactor for performance, extensibility, and feature completeness: resource pooling, pass culling, aliasing, and compilation caching.
- Introduces type-safe builder and context APIs, blackboard pattern, and unified resource management.
- Adds detailed documentation and cleans up obsolete files and APIs.
- Includes (commented) Unity Render Graph source for reference; not compiled, for parity and future extension.
Implemented a transient render graph system as a proof of concept, including resource aliasing, pass culling, and typed pass data. Added new project `Ghost.RenderGraph.Concept` targeting `.NET 10.0`.
Refactored graphics-related components:
- Simplified resource state transitions in `RenderingContext`.
- Improved resize handling in `GraphicsTestWindow`.
- Updated `D3D12GraphicsEngine` to streamline frame rendering.
- Enhanced `D3D12ResourceDatabase` and `D3D12SwapChain` for better resource management.
Added detailed documentation:
- `ALIASING.md` explains resource aliasing techniques.
- `API_DESIGN.md` outlines the render graph API design.
Updated solution to include the new render graph project.
