tmux.Snapshot.MarshalJSON() -> ([]byte, error)
```

MarshalJSON encodes the snapshot's tmux version and the records it holds. A kind it listed encodes as an array, empty when tmux reported none; a kind it never listed is absent. Those are different answers, and one field cannot spell both, which is why the arrays are pointers here. Nothing decodes; see [Session.MarshalJSON].
