now has a battleSound property mapping to appropriate audio assets. Adds 10
new MP3 files (arrows, cannon, catapult, gunfire-classic/modern, helicopter,

- Cap shieldBox at buildCost each turn in processCity
- Clamp displayed shields to min(shieldBox, cost) in city screen
- Add tests verifying shield capping and stalled build completion

chance (0.05 vs 0.15), increased growth rate, lowered max (0.4 vs 0.5)
- MIRV trunk continues flying toward its target after each split
