Skyward sortie director

Three complete selectable sorties: Fleet Patrol, Iron Horizon carrier defense, and Coastal Spear ground strike. Owns mission progression, island generation and matching terrain collision, ground target roles, bomber routing and anti-ship releases, SAMs and incoming guided missiles, countermeasure decoys, Viper 2 support, assisted carrier recovery, wreckage, radio text and per-player mission records. Combat owns target health, cannon projectiles and player guided weapons. Runtime system order 25 follows combat and precedes presentation/HUD. Reset frees every owned transient entity and GPU mesh. Mission grades persist through runtime_data.player; automated fixtures set testMode to leave player records untouched.
