notebooklm-cookie-refresh-cron-must-update-on-migration

The existing cookie-refresh.sh cron at /opt/shared/notebooklm-config/ writes cookies in notebooklm-py’s storage_state.json format. After migrating to upstream, this cron must be updated to write the new profiles/default/cookies.json format, OR replaced entirely by upstream’s nlm login CLI which handles auth natively via Chrome CDP.
