* Make EvolutionCriteria struct 8 bytes per object instead of 26 Unify LevelMin/LevelMax to match EncounterTemplate bubble up precise array type for better iteration * Inline queue operations, less allocation * Inline some logic * Update EvolutionChain.cs * Improve clarity on duplicate move check * Search reverse For a dual stage chain, finds it first iteration rather than second.
