Add 3 new hand-written bots to expand evolver seed pool: - phalanx (Rust, alpha island) - formation combat with aggression=0.85, economy=0.1 - assassin (Rust, alpha island) - decapitation strategy with aggression=1.0, economy=0.0 - opportunist (Go, beta island) - conditional aggression with aggression=0.55, economy=0.55 This brings the total seed count from 6 to 9, providing richer starting population across islands with diverse attack archetypes the evolver can recombine. Changes: - Add seeds/phalanx_strategy.rs.txt, assassin_strategy.rs.txt, opportunist_strategy.go.txt - Update seed.go with 3 new embed directives and seed entries - Add TestSeedPopulation to verify 9 seeds insert correctly - Update comments to reflect 9 seeds instead of 6 Co-Authored-By: Claude <noreply@anthropic.com>
