Operator-ruled per-machine virsh power. maas-node-power.sh + harness (24/24,
gauntlet 72 ALL GREEN): MAC-matched because MAAS renames machines at
enlistment, dry-by-default, every write verified by a real query-power-state.
Region prereqs fixed (no virsh there; maas profile was root-only -- created
via stdin login, key never printed). All 9 nodes powered and commissioning
end-to-end: 3 Ready / 6 Commissioning, shapes exact to D-121 Option C.
vr1-dc0-maas root retained but unused pending the stage-close D-103/D-123
amendment. G10 remainder: netem only.
CURRENT-STATE updated in this commit (GA-R1/C1).
