Desync Multiplayer Fix

Short Description Small MP fix for Stellaris 4. 3. 7. Originally made to address desyncs with Desynchronized Entries: country_resources, and later expanded to reduce Grand Archive and vivarium-related desyncs. Detailed Description This mod is intended for multiplayer games in Stellaris Cetus v4. 3. 7. Original issues addressed: Desynchronized Entries: COUNTRY_RESOURSES Desynchronized Entries: RANDOM_COUNT and NUM_EXHIBITS What the mod changes: 1. Disables the problematic randomized route logic for Caravaneer Fleet 3, which could cause OOS/desyncs in multiplayer saves. 2. Cleans up old fleet3_capital_destination route flags so existing saves do not continue using the broken logic. 3. Adds a workaround for Grand Archive and vivarium-related desyncs: increases vivarium capacity; heavily slows automatic space fauna growth; makes the controlled space fauna growth policy use safer behavior. 4. The vivarium workaround is intended to reduce desyncs involving entries such as RANDOM_COUNT and NUM_EXHIBITS, especially when the vivarium is completely full. Important: this mod changes the checksum, so every player in the multiplayer session must have the same mod version enabled.
