scripts/run-weekly-checkins.sh reads the admin API key from .env and POSTs the
Phase 3 batch endpoint (/discovery/coaching/run); a weekly host crontab entry
(Mon 08:00) invokes it. Running weekly services all cadences since the endpoint
skips users who aren't due. README documents the install. Output logs to
data/coaching-cron.log (gitignored).
