GymTag + GymEnemyRoster (+ GymRosterAuthoring) bake the gym singletons. New
DebugOp.SpawnEnemy (client SpawnEnemy wrapper + server receive case) spawns a
chosen enemy KIND (Drowner/Grindylow) from the baked roster near the sender —
replacing the wave-roster hack per the roadmap's Enemy-test GYM direction.
GoInGameServerSystem takes a GymTag branch: bypass the meta-catalog spawn guard
(a fresh gym has no CycleDirector) + seed a default Spark loadout on keys 1-4.
