Can `ChangeTracker` support other `RFC 6902` Operations?

Hey, thanks for the awesome work on this project!

OpenAI sends SSE events like this:

{
  "v": [
    {
      "p": "/message/create_time",
      "o": "replace",
      "v": 1761565519.397872
    },
    {
      "p": "/message/update_time",
      "o": "replace",
      "v": 1761565520.404756
    },
    {
      "p": "/message/content/parts/0",
      "o": "append",
      "v": "?"
    },
    {
      "p": "/message/status",
      "o": "replace",
      "v": "finished_successfully"
    },
    {
      "p": "/message/end_turn",
      "o": "replace",
      "v": true
    }
  ]
}

It would be great if ChangeTracker implementations could also support the RFC 6902 replace operation on Atom fields. What do you think?
