[BUG] /usage and /status return 429 rate limit after single request

Preflight Checklist

What's Wrong?

The /usage command returns a rate limit error after a single successful request. Steps to reproduce:

1. Open Claude Code (v2.1.69)
2. Run /status and navigate to Usage - works fine, data loads
3. Immediately run /usage again - fails with rate limit error
4. All subsequent /status or /usage calls also fail with the same error

Error message:

Error: Failed to load usage data: {"error":{"message":"Rate limited. Please try again later.","type":"rate_limit_error"}}

The rate limit on the usage endpoint appears to be extremely aggressive - a single request seems to exhaust the allowed quota, and subsequent requests fail even after waiting.

What Should Happen?

/usage and /status should be usable multiple times during a session without hitting rate limits. The usage endpoint should allow at least a few requests per minute for normal interactive use.

Additional Context

• Plan: Max
• OS: Ubuntu 24.04 (Wayland/GNOME)
• Claude Code version: 2.1.69
• claude.ai website shows usage data without issues, only the CLI endpoint is affected
• This started around March 2-3, 2026, coinciding with the Anthropic Usage Reporting outage (see status.claude.com history)
• The outage is marked as "resolved" but the aggressive rate limiting on the usage endpoint persists
