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.

 ### 2.2 Layers (层数)
 
 - Each player has one integer layer counter L per bond (23 counters). All start at 0 when the simulation starts, are never reset between rounds and are never reduced (no layer-loss effect exists in the data) [ASSUMED: never reduced].
+- `noStack: true` hides layer counts for 调和 / 协防干员 / 独行 / 绝技; it does not prohibit gains or clear stored layers. Their effects depend on member thresholds, but internal layers still participate in active-layer totals and unite ordering. [PRTS 下半盟约记录](https://prts.wiki/w/卫戍协议：盟约_下半/PRTS盟约记录): hidden-layer bonds still accept trait / strategy / equipment layer gains (review correction, 2026-10-04).
 - L is kept while the bond is inactive, but bond effects only apply while the bond is active (PRTS 盟约记录).
 - Wording contract used by every source: "使已激活的【X】层数+N" -> add only if bond X is active at the moment of the trigger; "（无需激活盟约）" -> add even if X is inactive. "自身所属盟约" = every bond of that operator; "自身已激活的盟约" = only its bonds that are active.
 - No layer cap in the data. Caps are per source: max_add_count_per_battle (layers a single garrison instance may add in one battle), max_layer (per round, e.g. 安洁莉娜 12/round). The official cap is in the client, not the data: `AutoChessBattleConst.MAX_GARRISON_STACK = 999`, `AddBondCount` stores `min(L + n, 999)` per bond (research 11 §1). Since 2026-10-01 (DESIGN §20.12) the remake stops each bond at 999 (`shared/constants.js BOND_LAYER_CAP`, `layerGainRoom`); the community agrees (巴哈姆特 12534 "每把都能999层", "沒999層的盟約情況下"; 12316 "999謝").
