f3s-storage skill: document zrepl replication liveness check (f0 cron canary)
f0 root crontab touches /data/nfs/nfs.LIVE_CHECK every 10 min, gated on
/data/nfs/nfs.DO_NOT_REMOVE. zrepl replicates zdata/enc/nfsdata to f1's
read-only sink every minute, so the file's mtime on f1 reveals replication
freshness (stalled if >~10-11 min behind). Added to zrepl.md and the hub
SKILL.md reference bullet.
