Two failures today were invisible: the ngit/Amber remote signer stalling
mid-push, and the deploy timer skipping while origin/main had moved.
- scripts/auto-deploy.sh records the reason for every skip (and the run time)
to ~/.local/state/skatespots-deploy/{last-skip,last-run}.
- scripts/ops-health.sh reads that back and prints repo/push sync, the skip
reason, the throttle window and timer health; exit 1 when action is needed.
--probe-push runs a bounded real push (the only true signer probe),
--notify desktop-notifies (deduped), --quiet is silent when healthy.
- Periodic watch: skatespots-ops-health.{service,timer} (every 15 min) plus
scripts/install-ops-health-timer.sh.
