Formation-based combat bot that moves all units as a coordinated group:
- Circular mean centroid computation (toroidal-aware)
- Hexagonal packing formation slots with greedy slot assignment
- Rally mode when mean distance from centroid exceeds 3 cells
- Scored movement: formation cohesion + advance toward enemy concentration
- Attack range bonus when engaging enemies in formation
- Self-collision avoidance via claimed destination tracking
- 10 unit tests covering all core algorithms
