test(@projects/@magic-civilization): 🐛 clear static _mcts_stats_log in before_each (isolation)

Browse source 
AiTurnBridge._mcts_stats_log is a static dict that persists across tests, and
get_last_mcts_stats does a most-recent-at-or-before-turn lookup — so a prior
test's player-0 entry ("rust_run_ai_turn") masked the expected heuristic
sentinel for the empty-cities player. Clear the static store in before_each for
deterministic isolation. Clears test_ai_turn_bridge_stats.
