fix(engine): set ZoneShrinkStep to 2 per plan §3.7.1

Browse source 
Plan §3.7.1 specifies ZoneShrinkStep = 2 for both 2-player and 3+
player matches. Previous implementation had ZoneShrinkStep = 1,
causing the zone to shrink too slowly and delaying the forcing
function that pushes bots into combat range.

- Update ConfigForPlayers() to set ZoneShrinkStep = 2
- Update DefaultConfig() to set ZoneShrinkStep = 2
- Update comments to reference plan §3.7.1

Closes: bf-1noo
