- Add csharp case to buildCandidate() with dotnet-script and mcs fallback
- Add defender_strategy.cs.txt seed file (combined Program.cs, Strategy.cs, Grid.cs)
- Add defender seed to population (gamma island, aggression=0.3, economy=0.4)
- Add csharp to langDisplayName() and update comments

- Updated fitness formula: fitness = 0.7*win_rate + 0.3*kill_rate (was win_rate only)
- Added kill tracking to ArenaResult: TotalKills, TotalMatches, KillRate
- Updated evolver system prompt to explicitly mention combat kills are valuable
- Enhanced arena logging to show kill rate and total kills
This change makes the LLM evolver select for combat aggression, not just win
optimization. The system prompt now informs bots that kills and eliminations
are part of the fitness evaluation, encouraging more aggressive strategies.

The evolver arena was using DefaultConfig() which has attack_radius2=12
for all matches. Per plan §3.4, 2-player matches should have
attack_radius2=36 (6 tiles) to achieve 65-80% combat density.
This bug caused evolved bots to learn energy-farming strategies since
enemies were rarely in attack range on 40x40 maps with only 3.5 tile
radius. With the correct 6-tile radius, bots will experience actual
combat during evolution and should develop fighting behaviors.
