wrangler types should include module declarations for default rules

### Which Cloudflare product(s) does this pertain to?

Wrangler

### What versions & operating system are you using?

Wrangler v4.10.0

### Please provide a link to a minimal reproduction

_No response_

### Describe the Bug

`wrangler types` should produce a `worker-configuration.d.ts` which has the module declarations for the default rules. For example:

```ts
declare module "*.html" {
const value: string;
export default value;
}
```

Right now, these are only being generated if I explicitly add them to my `wrangler.toml`:

```toml
[[rules]]
type = "Text"
globs = ["**/*.html"]
```

I shouldn't need to do that.

### Please provide any relevant error logs

_No response_

Start at the Wrangler `types` command and the code that generates `worker-configuration.d.ts`; compare default rule handling with explicit `wrangler.toml` rules. Run `wrangler types` without a custom rule and confirm that the generated output includes default module declarations such as `*.html`.
