jedarden	42e9561e46	feat(map-evolver): bias energy toward center, carve corridors to force contact Energy node placement now uses a tiered radius distribution: 30% in the contested central zone (0.05-0.20 from center), 40% in the mid-zone (0.20-0.40), and 30% in the home zone (0.40-0.60). Previously nodes were placed uniformly at 0.20-0.70, letting bots farm their home quadrant indefinitely without crossing the midline. After cellular automata wall generation, a 3-wide corridor is carved from each core straight to the map center, plus a 5x5 open arena at the center tile.

feat(map-evolver): bias energy toward center, carve corridors to force contact

Energy node placement now uses a tiered radius distribution: 30% in the
contested central zone (0.05-0.20 from center), 40% in the mid-zone
(0.20-0.40), and 30% in the home zone (0.40-0.60). Previously nodes were
placed uniformly at 0.20-0.70, letting bots farm their home quadrant
indefinitely without crossing the midline.

After cellular automata wall generation, a 3-wide corridor is carved from
each core straight to the map center, plus a 5x5 open arena at the center
tile. This creates lanes that funnel bots into contact — replicating the key
mechanic that drove frequent fights in the original AI Challenge Ants game,
where symmetric food spawning near the midfield forced both colonies to
expand outward and collide.

feat(map-evolver): bootstrap empty maps table and containerize

- Add seedIfEmpty: idempotent startup seeding (20 maps per player count,
  ON CONFLICT DO NOTHING) using cellular-automata generation + validate()
- Add continuous evolution loop across all player counts (2/3/4/6)
- ACB_MIN_SEED_COUNT and ACB_EVOLUTION_PERIOD configurable via env vars
- Add Dockerfile (lean Alpine build, no language runtimes)
- Add acb-map-evolver to acb-build.yml CI pipeline
- Add staging K8s Deployment manifest

Add map evolution pipeline (cmd/acb-map-evolver)

Phase 9 implementation: Map Evolution (§14.6)
- Parent selection weighted by engagement × vote multiplier
- Crossover with sector-based wall inheritance
- Symmetry-preserving mutation (wall flips, energy node shifts)
- Validation: connectivity, wall density bounds, energy node access
- Smoke test validation (simplified: connectivity + energy count checks)
- PostgreSQL maps, map_votes, map_fairness tables for lifecycle management
- Maps stored with status: active, probation, retired, classic
