feat(ModularBot): wall-bounce gun, 8 guns total

Browse Source 
- Wall-bounce gun: linear extrapolation with arena wall reflection
- Simulates enemy tick-by-tick, bouncing off walls (billiard-ball reflection)
- 4-iteration convergence on ticksToArrive like circular gun
- 8 guns: head-on, linear, circular, tsetlin, guess-factor, pattern, anti-surfer, wall-bounce
- Turret: #CCCCCC (silver), bullet: #EEEEEE (white)
