pub fn texture_storage(
    name: &str,
    binding_slot: u32,
    format: StorageTextureFormat,
) -> NodePort

Helper to create a texture storage port (read/write for compute shaders)

Example

let port = texture_storage("trail_map", 0, StorageTextureFormat::Rgba8Unorm);
let port = texture_storage("agent_map", 1, StorageTextureFormat::Rgba32Float);
