Translation support

**Context**

```json
"get_items": {
"name": "Get to-do list items",
"description": "Get items on a to-do list.",
"fields": {
"status": {
"example": "needs_action",
"default": "needs_action",
"selector": {
"select": {
// THIS
"translation_key": "status",
"options": [
"needs_action",
"completed"
],
"multiple": true
}
},
"name": "Status",
"description": "Only return to-do items with the specified statuses. Returns not completed actions by default."
}
},
},
```

The issue only identifies the get_items JSON selector and marks translation_key: status as the target; start by locating the generator or schema entry that consumes this selector metadata. Clarify the expected translated output, then use the repository’s existing tests or fixtures to verify that behavior once defined.
