Login
drwn login authenticates the CLI with Darwinian Auth Hub through the device flow.
The command uses the production Auth Hub by default. To test against another Auth Hub, set DRWN_DAH_HUB_URL:
DRWN_DAH_HUB_URL=https://darwinian-auth-hub-staging.dev-726.workers.dev drwn login
Emit machine-readable output:
drwn login --json
In JSON mode, the browser sign-in URL is written to stderr while stdout remains the final JSON success object.
On success, credentials are written to ~/.agents/drwn/credentials.json with owner-only permissions.
