GymSub bakes no WaveDirector (why sandbox enemies never spawned); the
sandbox's combat target is now a TargetDummyTag'd enemy ghost all five
EnemyAISystem passes exclude (planted; knockback stamps inert), spawned
at player+3m with 400 HP by an editor-only scene-gated server system,
dying through the normal Dying path and respawning 1.5s after the corpse.
EnemyTag-reuse audited: sandbox-only by design (cleared-checks would
count it elsewhere).
