Feature Request: Include Plan Usage Data in StatusLine JSON

Feature Request: Include Plan Usage Data in StatusLine JSON

Summary

Add plan usage data to the JSON provided to custom statusLine commands.

Problem

The /status command can show 5-hour plan usage (e.g., "54% used, resets in 26m"), but custom statusLine scripts cannot access this data because it's not included in the JSON input.

Proposed Solution

Add a plan_usage field to the JSON sent to statusLine commands:

{
  "plan_usage": {
    "five_hour": {
      "utilization": 54.0,
      "resets_at": "2026-02-15T01:00:00.977336+00:00"
    }
  }
}

Example

This would allow statusLine scripts to display:

[54% 26m]
^^^^^^^^
5hr usage & reset time

Why

• The CLI already fetches this data for /status
• StatusLine scripts can't access OAuth tokens to fetch it themselves
• Users want to see plan usage at a glance without switching to /status
