🔬 Nano-assemblers: 2D Self-Replication in a Fluid

2D Brownian-dynamics model of self-replicating nano-assemblers harvesting feedstock blocks in a viscous fluid, with Stokes-Einstein diffusion, an optical-trap tweezer you can drag, a kill-switch and exact mass bookkeeping. Compare measured doubling time with the handling-time limit.
