Per plan §3.7.1, the zone forces bots into contact. This change ensures
all built-in bots escape the zone FIRST when threatened (dist to zone
edge < 5 tiles), before any other action like energy collection or combat.
Changes:
- GuardianBot, SwarmBot, HunterBot: Added zone escape as Priority 1
- Phase 13 bots (Defender, Scout, Farmer, Pacifist, Phalanx, Raider,
Nomad, Opportunist, Assassin, Kamikaze): Added zone escape as Priority 1
- RandomBot: Added zone escape before random movement
The getZoneEscapeDirection function was already present and correctly
implements toroidal distance calculation with 5-tile safety margin.
Closes: bf-4m78q
- Add engine package with toroidal grid, game state, turn execution
- Implement focus-fire combat resolution with simultaneous deaths
- Add fog of war visibility filtering for bot state
- Implement energy collection (contested resources denied)
- Add bot spawning at active cores
- Implement win conditions: elimination, draw, dominance, turns
- Add replay JSON writer for match recording
- Add match runner with concurrent bot communication
- Add CLI tools: acb-local (match runner), acb-mapgen (map generator)
- Add comprehensive unit tests (26 tests passing)
Exit criteria met: can run complete 500-turn matches and produce valid replays
