Major overhaul of material palette management: - Added two-buffer indirection (PaletteOffsetBuffer, MaterialIndexBuffer) for GPU material lookup, with incremental upload and resizing. - MaterialPaletteStore now tracks dirty ranges, supports deferred slot reclamation, and exposes CPU-side arrays for upload. - ResourceManager manages persistent GPU buffers and uploads only dirty subranges per frame. - Updated HLSL and C# structs to use palette indices. - Refactored systems/components to use new palette index and release logic. - Added RenderContext.UploadBufferRange for partial uploads. Minor: Fixed StbIApi interop signatures, updated test namespaces, and performed code cleanups.
