OAuth token expiration is too short for Max subscribers

Problem

The OAuth token for Max subscription users expires too quickly, requiring frequent re-authentication via /login. This interrupts workflow and is frustrating, especially for users who use Claude Code throughout the day.

Current behavior

• Token expires after a short period (feels like every few hours)
• Users must run /login repeatedly to continue using Claude Code
• No way to configure token expiration duration

Expected behavior

• Longer token expiration for Max subscribers (e.g., 7 days or 30 days)
• Or a configurable token lifetime setting
• Or a refresh token mechanism that silently renews the session

Environment

• Claude Code CLI
• Max subscription plan
• Running on Linux (Synology NAS)

Thank you for considering this improvement.
