feat(rendering): add GPU scene updates and optimizations

Added a new `code-executor` agent with strict TDD and performance focus. Refactored `TextureProcessor` and `TextureAssetHandler` to use `Magick.NET` for image processing. Enhanced `GPUScene` with `InstanceCounterBuffer` and improved instance management. Introduced a compute shader for GPU scene updates. Updated `GhostRenderPipeline` to handle add/remove instance buffers.

BREAKING CHANGE: Removed `x86` platform support and replaced `CachesFolderPath` with `LibraryFolderPath`. Updated project dependencies and removed unused utility classes.
