Get root data via `$` or parent data via `..`

{
  "dep": 2,
  "gov": [
    {"name": "Chris", "age": 23, "city": "New York"},
    {"name": "Emily", "age": 19, "city": "Atlanta"},
    {"name": "Joe", "age": 32, "city": "New York"},
    {"name": "Kevin", "age": 19, "city": "Atlanta"},
    {"name": "Michelle", "age": 27, "city": "Los Angeles"},
    {"name": "Robert", "age": 45, "city": "Manhattan"},
    {"name": "Sarah", "age": 31, "city": "New York"}
  ]
}

如何通过JSON query转为

[
    {"name": "Chris", "age": 23, "city": "New York","dep": 2},
    {"name": "Emily", "age": 19, "city": "Atlanta","dep": 2},
    ......
  ]

No implementation files or tests are named. Start by reading the repository's existing JSON query syntax and examples, then trace how nested object and array contexts are evaluated. Done means supporting root or parent references so each object in gov includes the top-level dep value, with coverage for the provided example.
