Pre-FTL Conquest & Infiltration: Enhanced

Overview In default (unmodded) Stellaris, when a player conquers a pre-FTL planet (or ringworld segment), he/she is given free districts based on the number of Pops conquered. The city districts are the wrong type for machine and hive empires, and players receive farming districts on worlds that previously housed a lithoid pre-FTL civilization. Despite many changes in 3. 7 "Canis Minor" for infiltrated and enlightened pre-FTLs, most pre-FTLs still do not receive districts based on what food they consume. The AI does not receive any bonus districts or buildings except for pre-FTL enlightenment. It's my opinion that these free districts represent repurposing existing infrastructure for the conqueror's use. To that end, this mod gives the proper type of city, nexus, or hive districts as appropriate for the conquering empire type. Second, planets (or ringworld segments) inhabited by lithoid civilizations receive mining districts as opposed to farming districts. Rogue servitors get organic sanctuaries instead of some of the nexus districts, because preserving some developed areas allows bio-trophies to live in their "natural habitat." Finally, the AI benefits from these free districts in order to even the playing field. A Bit More Detail This mod started as a response to four very specific, small areas: When conquering pre-FTL planets, human players get free districts to employ about half the population, but the AI does not Machine Empires and Hive Empires are given city districts instead of the appropriate nexus or hive districts When conquering a lithoid pre-FTL planet, the player is given farming districts, which lithoids don't need Necrophage AI players have a special helper event to gain control of pre-FTLs, but it is not actually conquest and thus misses out on some things To address these issues, this mod re-implements (for both players and AIs) free districts upon acquiring a pre-FTL planet. The improved "pre-FTL transfer" code generates the appro
