Combat: enemy attack telegraph - ground danger cones (MC-4 clarity)

Browse Source 
CombatFeedbackSystem.UpdateEnemyDanger paints a red ground danger cone at each enemy while its AttackWindup counts down -- oriented along the enemy facing, sized to EnemyStats.AttackRange, brightening + scaling as the strike nears (intensity = 1 - ticksRemaining/22) so the player reads WHERE + WHEN to dodge. Client-only observe-only; one pooled mesh per winding-up enemy, pruned each frame. Play-verified (14-enemy wave, 8 telegraphs at once, zero errors).
