Steps to reproduce

Create a .vue SFC file and add defineModel clause with default value set

<script lang="ts" setup>
// ...

/**
 * Should the modal be open?
 */
const isOpen = defineModel<boolean>('isOpen', { default: false })
</script>

Run the component through the basic checker and observe lack of default value in returned object.

What is expected?

{
    "default": false,
    "name": "isOpen",
    "global": false,
    "description": "Should the modal be open?", 
    "tags": [],
    "required": false,
    "type": "boolean",
    "declarations": [],
    "schema": {
        "kind": "enum",
        "type": "boolean",
        "schema": [
            "false",
            "true"
        ]
    }
}

What is actually happening?

{
    "name": "isOpen",
    "global": false,
    "description": "", // Also no description - see https://github.com/vuejs/language-tools/issues/4592
    "tags": [],
    "required": false,
    "type": "boolean",
    "declarations": [],
    "schema": {
        "kind": "enum",
        "type": "boolean",
        "schema": [
            "false",
            "true"
        ]
    }
}
