f3s-storage skill: document the zusb removable quarterly backup pool
zusb is a 4-disk raidz2 USB-SATA pool used as offline backup storage,
loaded ~once per quarter. Migrated from t450 to the f3s USB-key scheme:
zusb/data/enc rekeyed to a raw key on /keys/zusb.key, scripts on all
f-hosts. Note added to usb-keys.md and the hub SKILL.md.
