"""LangGraph entrypoint that polls open agent PRs for CI failures / conflicts.

A fallback for deployments where CI webhooks (``check_run`` / ``workflow_run``)
aren't reliably delivered, and the only path that can react to base-branch
merge conflicts (GitHub emits no webhook for those). Register it on a cron to
sweep periodically; each tick calls :func:`agent.ci_autofix.sweep_open_prs`.
