jedarden 700c37bf0f fix(engine): reduce spawn radius to force immediate combat (plan §3.7.1)
Reduced 2-player spawn radius from 0.20 to 0.15 (8 tiles → 6 tiles apart)
to ensure bots start within attack range (6 tiles). Previously, idle bots
started 8 tiles apart and died to the zone without fighting (0 combat deaths).

## Changes
- engine/match.go: primaryRadius 0.20 → 0.15 for 2-player matches
- Bots now spawn exactly 6 tiles apart = attack radius
- Idle vs idle: 2 combat deaths (mutual destruction) vs 0 before

## Testing
- idle vs idle: 100% combat deaths (was 0%)
- TestCombatDensityMetrics: 83% combat rate (plan target: 65-80%)
- All engine tests pass
