Write Section 5 of edu/markov.md: Exercise 2 — Simulating a Random Walk\n\nLearning objectives:\n- Model a countably-finite state space (bounded integers) in Rust\n- Implement reflecting boundary conditions\n- Aggregate results from many trials into a histogram\n\nContent to produce:\n- Setup instructions (reuse or extend Exercise 1 project)\n- Step-by-step hints:\n  1. Define RandomWalk with min, max, prob_right fields\n  2. Implement step with boundary reflection (clamp or reverse)\n  3. Implement histogram by running simulate() many times\n  4. Print histogram as ASCII bar chart\n  5. Observe convergence toward uniform (symmetric walk) or skewed (asymmetric)\n- Full reference solution\n\nTarget: replace the stub in edu/markov.md §5
