Combat stats round 5: final nudges and convergence policy

Round 4: mirrors 0-3%, swarm vs cruisers +7%, glass vs armored
resolved at +3% for armored (armor 1200 confirmed). Noise floor
established at ~+/-10% per single run (battleship margin ignored a
-10% EHP cut; repair drifted 14->24% with no repair changes).

Round-5 nudges for the armor-coupling overshoots: battlecruiser hull
2000 -> 2200, dreadnought/carrier 22500 -> 24000 (two-round
persistent deficit vs destroyers). The battleship's +23% over a pure
frigate fleet is accepted as doctrine texture rather than chased: the
edge is mechanical (range) and the fair anti-capital answer is the
mixed fleet, whose arena is balanced. Convergence policy documented:
act only on two-round signals, +/-20% counts as converged for v1.
