• guides you through anthropic oauth (pkce)
• prints an access token to stdout and exits
• caches tokens at ~/.config/crush/anthropic and reuses them on later runs
• if a cached token is still valid, it prints immediately and exits
• if expired and a refresh token exists, it refreshes, saves, prints, and exits
