Per the rules ("Бомбардировка планет"), a planet is bombed from the
strongest attacking power downwards, and a planet bombed to extinction
keeps its material and capital stockpiles but loses its working industry.
ProduceBombings now sorts attacking races by total bombing power
(descending) instead of iterating the attacker map in random order, and
on a wipe zeroes the planet's industry (Free already keeps capital and
material). bombingPower is extracted as a shared helper.
The rules already describe both, so no documentation change. Tests:
bombing order by power, and industry collapse with capital/material kept
on a wipe.
