## what it does

- starts a local server and auto-opens your browser
- 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
