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
