Feature Request - refresh status line on an interval

[dhughes]

It would be very helpful if the statusline script could be configured to automatically refresh on an interval. Right now it only updates after you interact with Claude.

As an example, I added a statusline script that will check Github to see the status of the PR associated with the branch I'm working on. I would like that status to update every minute or so, even if there hasn't been any activity in Claude code. I often leave it Claude code idling in a terminal window and hop back to it when I need it. If I haven't interacted with Claude code for a while, the status line can be out of date.

I imagine a refreshIntervalSeconds setting like this:

{
  "statusLine": {
    "type": "command",
    "command": "ruby ~/.claude/statusline.rb",
    "refreshIntervalSeconds": 30
  }
}

This would cause my statusline script to be run at least every 30 seconds, even if there hasn't been any activity within my Claude code session.
