- Add capture-dsh-token.sh script that captures the dsh-web launch token - Add login endpoint (/dsh-web-login on :8081) that mints 30-day auth cookie - Document the authentication flow in zulip-health.prose.md (Platform B4) - Cookie is authority-bound to 127.0.0.1:3080 with 30-day expiry - After first login, subsequent requests use the cookie — no token required
