Setup and evaluation

Use CartPole to verify that a reinforcement learning training loop can handle observations, discrete actions, and episode boundaries. Compare average episode length across fixed evaluation seeds instead of reporting a single successful run.

Install with pip install gymnasium. Create the environment with gymnasium.make('CartPole-v1'). Rendering is optional and uses the classic-control extra.
