Economy checks: consumer demand derived from shared uses; a weapon's draw is a sink

ConsumerDemand drops the two-or-three-step window (rulings consumer-demand-shared-only,
consumer-demand-skips-final-assemblies): a processed good owes a consumer use when it is
shared, derived from the recipe graph each check. A weapon's draw of a round is one use
(ruling draw-is-one-use). SourceSink counts a drawn commodity as sunk. Drawn is the one
reader of offered designs' WeaponData.AmmoType. Tests are unrun at this commit.
