- Major optimization of Ghost.RenderGraph.Concept: pooled resources, zero-allocation hot paths, explicit queue types, and batch barrier APIs. - Migrated Ghost.DSL shader compiler to ANTLR4-based parser; removed hand-written parser, added grammar files and semantic model conversion. - Added CollectionPool/ListPool for pooled list management. - Updated documentation for new architecture and performance. - Removed Ghost.Shader.Concept (material/material system) from repo and solution. - README.md replaced with a brief project statement.
