A fresh attempt2 re-fetched every article (minutes + dollars) just to
re-deliver a result whose data was already archived and pushed. attempt2
now extracts session_id from the failed envelope and runs
claude --resume with a short re-deliver prompt (no re-collection, no
browser); heartbeat is not reset in resume mode. attempt3 (fallback
provider) stays a fresh full run — cross-provider resume not trusted.
