Combat stats round 4 from arena round 3 margins

Round 3 (narrow lanes; arena geometry is part of the fixture from
here): dreadnought closed to -11%, battleship improved to +22%, the
drone swarm flipped to +14% over cruisers under full engagement, glass
beat armored for the third consecutive round, mirrors/repair/
two-to-one healthy, stations cracked at 51% by the 3x swarm under the
new geometry (watch, not touched).

Round-4 knobs: armor_plates 1000 -> 1200 (~37 HP/threat; persistent
glass signal, also lifts armor-carrying cruiser/BC/destroyer/DN
loadouts), battlecruiser hull 2500 -> 2000 (net -300 EHP after its
armor gain), battleship 7000 -> 6300 (loadout has no armor, clean
-10%), dreadnought/carrier 19000 -> 22500 (opposing destroyers gain
armor too, so the larger step). Anchors doc notes the emerging shape:
the arena prices capitals as tanks with taxed guns.
