Feature request: /usage command to show token consumption across sessions

Summary

There's currently no way to check token usage across sessions from within Claude Code. The only option is /cost which only covers the current session.

Proposed feature

Add a /usage command (or similar) that shows:

• Tokens used in the current session
• Tokens used today (across all sessions)
• Remaining tokens before hitting the current rate limit
• Reset time for the current limit window

Current workaround

Users have to leave the CLI and go to console.anthropic.com to check usage — which breaks the flow when you're deep in a coding session and just want a quick sanity check before starting a large task.

Why this matters

When working on long tasks or batch operations, it's useful to know how close you are to the limit before committing to a large context operation. Right now it's a blind spot.
