fix: genome GA converges via BFS fitness + two-rate prefix-aware mutation
- Replace Manhattan distance with BFS distances (actual maze path length)
- Switch from NN to direct sequence genome (what YouTube Shorts actually use)
- Mutation-only GA (crossover breaks positional maze paths)
- Two-rate mutation: low rate before best-step (preserve prefix), high after (explore tail)
- Auto-seed selection finds maze with short BFS path
- Default maze 15x15, cell_size=36, max_steps=150
- Typically converges in 5-15 generations
