Replay harness: a --to bound and the homelab window driver

edge-bench --group and replay:corpus take --to <article> next to --from, so a
replay covers one window of a group's history while the corpus holds others
(the 2016 ranges next to 2021's and 2025's). deploy/replay-window.sh runs a
window on homelab: every group whose window ranges are all stored is replayed
once into usenet_replay through the voyager-3 app image, 4 groups at a time,
looping while the corpus fill completes the rest.
