Feature Request: Expose account usage limits in status line JSON input

Feature Request

Summary: Add daily and weekly account usage limits to the status line JSON input.

Current Behavior

The status line JSON input currently includes only session-specific data:

• context_window (tokens used in current session)
• cost (session cost in USD)
• model, workspace, session_id, etc.

The /status command shows daily and weekly usage limits, but this data is not available in the status line JSON input.

Requested Behavior

Add account-level usage limits to the status line JSON input, for example:

{
  "account_limits": {
    "daily": {
      "used": 50,
      "limit": 100,
      "percentage": 50
    },
    "weekly": {
      "used": 200,
      "limit": 500,
      "percentage": 40
    }
  }
}

Use Case

Users want to monitor their daily/weekly usage limits directly in the status line to avoid hitting rate limits unexpectedly. Currently, users must run /status manually to check this information.

Example Status Line Output (if implemented)

my-project | Ctx: 15% | $0.86 | Daily: 50% | Weekly: 40%

This would provide at-a-glance visibility into account quotas without interrupting workflow.
