Zerg Swarm origin
Adds the Zerg race as an origin to Stellaris, implemented as a Devouring Swarm starting on a Hive World. The Zerg trait makes their leaders immortal and their pops extremely adaptable (+200% habitability like machines), allowing them to quickly colonize and expand. This origin starts with the prerequisite tech unlocked for both the Hive Worlds and Engineered Evolution ascension perks. Updated to 3.8.3.
