- 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.
