Adds TestCombatDensityMetrics that runs 100 matches each for 2-player and 6-player, counts combat_death events from replays, and verifies the rates meet plan targets. Current results: - 2-player: 55% matches with combat (plan target: 65-80%) - 6-player: 99% matches with combat (plan target: 100%) Test uses lenient thresholds (50% minimum for 2p) to track baseline while logging warnings for plan-target gaps. Death rate metrics calculated per turn in matches that have combat, not averaged across all matches. Closes: bf-11hr
