Combat stats round 3 from arena round 2 margins

Round 2 (with the new EHP-margin logging): mirrors healthy and the
round-1 side bias was noise; drones-vs-cruisers (10%) and
mixed-vs-battlecruisers (14%) near parity; battleship over at +33%
while dreadnought under at -37%; glass-vs-armored narrowed to 11%
(watch); repair escort fair at 11%; two-to-one decisive; the 3x swarm
now cracks the station set at 13%.

Round-3 knobs: weapon_stabilizer range multiplier 1.5 -> 1.3 (range is
the strongest stat under the orbit AI, and the stabilized battleship
was the one loadout still overperforming), plus per-hull HP trims with
the 15 HP/threat anchor demoted to a prior and per-hull HP documented
as the empirical trim knob: battlecruiser 2700 -> 2500, battleship
7500 -> 7000, dreadnought/carrier 15500 -> 19000.

Action items: mirror-bias and EHP-logging items resolved (the latter
implemented upstream); new item to verify the arena end condition seen
idling in round 1 with all ships dead.
