Feature Request: Status Line Position Option (above/below input)

Summary

I'd like the ability to position the status line above the input line instead of only below it.

Current Behavior

The statusLine setting in settings.json only supports:

• type: "command"
• command: path to script
• padding: number

The status line is hardcoded to display at the bottom of the interface.

Requested Change

Add a position option to the statusLine configuration:

{
  "statusLine": {
    "type": "command",
    "command": "~/.claude/statusline.sh",
    "position": "above"
  }
}

Values:

• "below" (default) - current behavior
• "above" - display above the input line

Use Case

When tracking costs and tokens in real-time via a custom status line script, having this information above the input area makes it more visible and easier to monitor while typing. The current bottom position can feel disconnected from the active work area.

Example Status Line

$0.52 │ In: 8.5k Out: 1.2k

This would be a simple configuration addition that gives users flexibility in their workflow preferences.
