Converted entity materials to new fade shader Implemented visibility system Refactored per-instance entity code to run inside monobehavior on entity instances Created state machine AI for enemy ships with basic patrol and combat routines Removed legacy AI code (controller item behaviors) Added automatic trigger group assignment for matched weapons Created ship collision system Created shield VFX and colliders
