Module node 

Handles for Vulkan smart-pointer resources.

When you bind a resource to a Graph, you get back a node handle:

let buf_node: BufferNode = graph.bind_resource(my_buffer);
let img_node: ImageNode   = graph.bind_resource(my_image);

These handles are then passed to command-building methods like resource_access or shader_resource_access.

Node kinds

Handle	Resource type	Use case
BufferNode	Owned Buffer	Most common
ImageNode	Owned Image	Most common
AccelerationStructureNode	Owned AccelerationStructure	Ray tracing
SwapchainImageNode	SwapchainImage	Swapchain presentation
BufferLeaseNode, ImageLeaseNode, AccelerationStructureLeaseNode	Pool-leased resource	Pool-based allocation
AnyBufferNode, AnyImageNode, AnyAccelerationStructureNode	Any of the above	Heterogeneous collections

For most users, BufferNode and ImageNode are all you need. The Lease and Any* variants exist for advanced pooling and dynamic dispatch scenarios.

When borrowing resources back out of a graph with Graph::resource, concrete node types return the exact stored handle type, while Any* node types return a borrow of the underlying resource. For example, BufferNode yields &Arc<Buffer>, but AnyBufferNode yields &Buffer.
