Sync pbs/zfs-health-check.sh to the deployed version and log the full
INC-001 resolution arc:
- recovery by importing pools on stable /dev/disk/by-id paths
- by-id cachefile pin so the fix survives USB re-enumeration
- wait-for-zfs-usb.sh + zfs-import-cache drop-in for the boot race
- alert split: devices-present (import) vs devices-absent (hardware),
new zfs_pool_members_present metric
- cron ownership fix: root-managed single entry, tommy evicted, unmarked
root line removed (double-fire root cause)
Marks the acute import/alert half of INC-001 resolved; USB-hub reliability
history retained as a separate hardware concern.
