Reorder bindings

```wgsl
@group(0) @binding(0)
var X: array;

@group(0) @binding(1)
var W: array;

@group(0) @binding(2)
var B: array;

@group(0) @binding(3)
var Y: array;
```

Our kernel preamble currently looks like the following, seems fine right? WRONG!
In reality, you want your bindings ordered in ascending order of change.

What does that mean?
Your `read_write` bindgroup should be `@group(0) @binding(0)`, because every operation has a single output.
Simple, but boring change to make throughout the codebase.

Start by locating the kernel preambles referenced in the issue and inspect each binding's access mode. Reorder every bind group so read_write output bindings use the lowest binding number, then verify that the ordering is consistent throughout the codebase.
