Upload a DroneLang script to an autonomous drone (DroneLang is a simple scripting language. Scripts run once per tick. The drone executes the first matching IF branch as one game action. MOVE and at() accept either a POI ID or its station/base ID. MOVE stays within the current system. ATTACK starts a battle only against a visible target at the drone's POI; it can join the battle in its system against any participant. DEPOSIT unloads into storage at the drone's current station. Every deployed drone under control runs its script; drone_control raises drone damage, accuracy, mining yield, and repair by 1% per level. Pass empty script to clear.)
