OAuth token missing user:profile scope - /usage fails on Linux

Description

The /usage command fails with a permission error on Linux. The OAuth flow does not request the user:profile scope, but /usage requires it.

Steps to Reproduce

1. Install Claude Code 2.1.39 on Linux (Ubuntu 24.04)
2. Authenticate with claude (completes OAuth flow in browser)
3. Run /usage inside a session

Expected Behavior

/usage displays usage data.

Actual Behavior

Error: Failed to load usage data: {"type":"error","error":{"type":"permission_error","message":"OAuth token does not meet scope requirement user:profile","details":{"error_visibility":"user_facing"}},"request_id":"req_011CY2LhjcE9MA43E3asVXeo"}

Notes

• Same version (2.1.39) works fine on macOS — the macOS Keychain credential has the correct scopes
• Logging out and re-authenticating on Linux does not fix it — the new token still lacks the scope
• All other functionality works correctly; only /usage is affected

Environment

• Claude Code: 2.1.39
• OS: Ubuntu 24.04 (GCP VM)
• Auth: OAuth (not API key)
