Generation never offers gear no hull can mount

Operator ruling, 2026-09-30, on the Autocannon: "Leave the autocannon unsold,
we'll need to author a bunch more hulls before all the gear variety in the game
has a home." The fit rule gets one owner, HardpointData.Takes (the gear's type,
laid in at the hardpoint's rotation, filling every cell); LoadoutGenerator's
hardpoint picks, its reuse of a previous product and `AetherDb hardpoint-fit`
all read it. RandomProducts, which both station stock and NPC loadouts draw
through, offers only gear with a home: Tool gear, hulls, or hardpoint gear some
hull in the catalog takes. The Autocannon keeps its product and price.

Test: the Autocannon is never drawn in 2000 draws of its hardpoint type; after
a scratch hull whose hardpoint takes it is authored, it is.
