Implements complete SwarmBot formation-based combat strategy in AssemblyScript: - JSON parsing for game config and state - Tight cohesion (radius=3) movement with circular mean center-of-mass - Enemy-seeking behavior with engagement bonuses - Toroidal distance calculations Builds to 27KB swarm.wasm (AssemblyScript produces compact binaries vs Go's ~12MB). Build script now copies to dist/. Closes: bf-2a7w Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
