Refactor instance update flow, asset registry, and texture IO

Browse Source 
- Renamed AddInstanceRequest to UpdateInstanceRequest; unified add/update logic for GPU instances
- Introduced UpdateGPUInstanceSystem to handle changed MeshInstance components
- Replaced QueryBuilder.Create() with QueryBuilder.New() for consistency
- Switched versioning in ChunkView HasChanged/HasStructuralChanged to uint
- Added extension-to-AssetType mapping in AssetHandlerRegistry
- Changed TextureAssetHandler/Processor to use nint for image data
- Enhanced DDS cache: read mipmap count, handle invalid files
- Updated ProjectBrowserViewModel to use IAssetRegistry
- Upgraded Misaki.HighPerformance and System.IO.Hashing packages
- Set DependencyChainCapacity in JobSchedulerDesc
- Fixed instance buffer logic in GhostRenderPipeline
- Miscellaneous cleanups and namespace improvements
