feat(render): add meshlet rendering and ECS query ref API

Introduces meshlet-based rendering pipeline with new HLSL structures and push constant layouts. Refactors meshlet upload/cooking, updates RenderGraphContext for global/view/instance data, and enhances ECS QueryBuilder with ref returns and [UnscopedRef] for fluent chaining. Improves resource management and disposal patterns, updates D3D12 interop for compatibility, and refines test/app infrastructure. Includes dependency updates, bug fixes, and code cleanups.
