[BUG]: drizzle-arktype createSelectSchema typing doesn't accept refinements for custom columns

### Report hasn't been filed before.

- [x] I have verified that the bug I'm about to report hasn't been filed before.

### What version of `drizzle-orm` are you using?

1.0.0-beta.10

### What version of `drizzle-kit` are you using?

1.0.0-beta.10

### Other packages

drizzle-arktype 1.0.0-beta.10

### Describe the Bug

If I specify a view field like:

```ts
{ x: sql`${t.x} * 2`.as('x') }
```

and then try to create a refinement for createSelectSchema to type column `x` like:

```ts
createSelectSchema(myView, { x: type.number })
```

then Typescript complains with:

`Object literal may only specify known properties, and 'x' does not exist in type 'NoUnknownKeys>'`

Typescript is satisfied if I get rid of the `.as('x')`, but then queries don't work:

`error: You tried to reference "x" field from a subquery, which is a raw SQL field, but it doesn't have an alias declared. Please add an alias to the field using ".as('alias')" method.`

I've also tried various versions of aliasing to different names (e.g. `.as('y')` and/or using 'y' as the key in the refinement) to no avail.

Typescript 5.9.3
