jedarden f664c93966 fix(engine): correct 2-player spawn radius to 25% per plan §3.7.1
Previous spawn radius of 10% (2 tiles from center) put bots only 4 tiles
apart on a 40x40 grid - within the 5-tile attack radius. Bots killed each
other immediately on turn 1 instead of being forced together by the zone.

New spawn radius of 25% (10 tiles from center, 20 tiles apart) puts bots
outside attack range. The zone forcing function now works as designed:
bots start apart, zone shrinks over time, and combat occurs when bots are
forced into contact range.

Verification:
- rusher vs rusher: combat deaths on turn 3 after moving into range
- rusher vs gatherer: combat deaths on turn 6
- Zone activates at turn 10, shrinks by 2 tiles/turn to min radius 2

Closes: bf-4qg4
