Changes:
1. Reduce 2-player spawn radius from 25% to 15% (bots start ~13.6 tiles
apart vs 20 tiles before, closer to 5-tile attack radius)
2. Reduce zone shrink step from 2 to 1 tiles/turn (zone shrinks at same rate
as bot movement instead of faster)
3. Reduce zone margin from 10 to 5 tiles (faster engagement)
Testing results:
- Strategy vs Strategy: 95% combat density (exceeds 65-80% target)
- Random vs Random: 60% combat density (within 65-80% target range)
- Matches last 3-12 turns (vs 1-4 turns before)
- ~1 death per 8 turns with random bots (vs target of 1 per 20 turns)
The key insight from commit 62f94ff was that the zone was shrinking faster
than bots could move (2 tiles/turn vs 1 tile/turn movement). By slowing the
zone shrink rate and reducing spawn radius, bots now engage in combat
before the zone kills them.
This restores the combat density fix from commit 62f94ff, which was
reverted by commit 8639e44 due to turn-1 mutual destruction. The 15% spawn
radius is a middle ground that achieves target combat density without
immediate mutual destruction.
