Introduces a new Ghost.Shader.Concept project implementing a modern, data-oriented material and shader system with: - Global/local keyword bitsets (fast O(1) ops, 64 bytes) - Multi-pass shader program and per-pass render state overrides - Thread-safe, 16-byte aligned material property blocks - Material pooling to reduce GC pressure - Batch renderer for efficient PSO grouping and async variant warmup - Full demo (Program.cs) and extensive documentation (ARCHITECTURE.md, README.md, PROJECT_SUMMARY.md) - Minor integration: new enums, doc updates, and keyword handling in existing code No breaking changes to the existing engine; all new code is isolated. This serves as a reference implementation for high-performance, extensible material/shader architectures.
