Bug when using `prefixItems` + `items: false` + `default` in JSON Schema

When defining a JSON Schema that combines prefixItems, items: false, and a default value for an array, and referencing it via $ref, the library fails to process the schema.
The schema is valid according to JSON Schema 2020-12, but triggers an internal error in the library.
Removing any one of these three elements prevents the bug.

Steps to Reproduce

Original schema causing the bug: schema_cat.json
Minimal schema that still triggers the bug:

{
  "$defs": {
    "T": {
      "type": "object",
      "properties": {
        "x": {
          "type": "array",
          "prefixItems": [
            { "type": "integer" }
          ],
          "items": false,
          "default": [0]
        }
      }
    }
  },
  "$ref": "#/$defs/T"
}

This works correctly (no error) when $ref is not used:

{
  "type": "object",
  "properties": {
    "x": {
      "type": "array",
      "prefixItems": [
        { "type": "integer" }
      ],
      "items": false,
      "default": [0]
    }
  }
}

Using typify::import_types! and passing in either schema fails at comptime with error: value does not conform to the given schema.

Expected Behavior

The library should correctly parse the schema and validate default values.

Observed Behavior

The library throws an error or fails to process the schema when all three conditions (prefixItems, items: false, default) are present and used via $ref.

Environment

• typify 0.5.0
• rustc 1.92.0

I think that's all I could find out via my testing, let me know if anything else could be of use in debugging this.

Reproduce the comptime failure with the minimal schema and typify::import_types!; compare it with the equivalent schema without $ref. Trace the schema import and default-value validation paths, then confirm that both forms parse successfully and validate the [0] default without an internal error.
