Previous Changes (2026-03-26)

Fixed math bug: replaced broken Taylor series sin/cos approximations with math.Sin/math.Cos in engine/match.go and cmd/acb-mapgen/main.go. The Taylor series produced incorrect results for angles > π, causing incorrect core/energy/wall placement in 3+ player maps.
Replaced random wall scatter with cellular automata wall generation in cmd/acb-mapgen/main.go:
- Seeds full grid at 40% density
- Runs 4 iterations of B5/S4 cellular automata smoothing
- Enforces rotational symmetry by mirroring sector 0
- Thins to target density
- Protected zones around cores (3-tile radius) and energy nodes
- Produces natural cave-like wall structures instead of scattered dots
Added comprehensive map generation tests (cmd/acb-mapgen/mapgen_test.go):
- Connectivity validation across all player counts and 10 seeds each
- Core count and ownership verification
- Energy node/wall non-overlap
- Wall density bounds checking
- Disconnected map detection (BFS validation)
- Small grid generation
- Determinism (same seed = same map)
