Caps consistencyCap at the largest day the consistency rule would have
allowed (profitTarget × consistency). Prevents previous overshoots or
losses from expanding future targets beyond what consistency permits.

Day 1: min(remaining × consistency, profitTarget × consistency)
Day 2+: min(maxDay, profitTarget × consistency)
