New Models:

Pompey, Gracchi, Agrippa, Tiberius

Key changes:

• Memory is now dynamic, inherited, and mutates across generations (previously hardcoded influence from past inputs).

• Creatures now count nearby similar and dissimilar colors instead of just checking for their presence.

In addition, all of these models have their duplicates spawned behind them instead of at random locations on the grid, like in some earlier models.
