Expensive Immortal Bots

This mod transforms bots into a true endgame objective for repopulating your colony. Bots no longer lose durability, making them a permanent investment. To balance this, the total cost is 100 times higher: parts are 10 times more expensive to produce, and final assembly requires 10 times more resources and time. Operational stats are also scaled up: bots possess 10 times the energy and fuel storage, but they also consume fuel at 10 times the rate and require 10 times longer to charge.
