Implements the unattended episode loop described in docs/deploy.md but not
yet built. run_campaign.py boots a fresh VM per episode, drives the full
phase schedule via the existing EpisodeRunner/VMLoadController stack, writes
campaign.json atomically after each episode, and signals completion with
campaign_done.marker. shipper.py watches data/episodes/ for done.marker
files, tar+zstd-compresses each, and PUTs them to the receiver with
exponential backoff on failure. Both support SIGTERM gracefully, finishing
the current episode/scan before exiting.
