Forgejo #16, part 3 of #12. BuildController deducted the cost from the bank at the moment of purchase and refused outright with "Not enough rocks", so nothing ever had to be delivered anywhere. Each building now carries its own stock, and an order it cannot pay for yet is QUEUED and completes by itself once ore arrives. Records get an `id` because a building has to be referable across the space <-> planet-surface scene swap, when every Building NODE has been destroyed and rebuilt. Position would nearly work and then fail on two buildings placed on the same spot. Production advances in the GameState autoload, the same way extractor haulers already do, so an order can complete while the player is down a gravity well. A finished vessel becomes `ships_owed` rather than being handed straight to a Fleet that may not exist, and the fleet claims what it is owed when it next has room. The craft menu remembers which crafter it was opened for: _process() clears current_building while any menu is open, so by the next frame the menu would no longer know. It shows the ore delivered HERE rather than the bank, since showing the bank would promise something the crafter cannot actually build. Ship crafting cannot be supplied until #17 lands - nothing yet moves ore into a building. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
