灵巧's knocked-out aura counts only knocked-out operators; hidden-layer bonds hide their layers in the UI only (#66)

A knocked-out 灵巧 operator gives its neighbours the aura once more; a player retreat, a merchant exit or a 联防 forced exit no longer counts, and a redeploy restores it. 调和, 协防干员, 独行 and 绝技 hide their layer counts in the UI while the real layers stay for saving, settlement and support ranking.
