feedback6: merge R21D — with both slots full, every consumable (博士投影, 盟约之币 …) opens the replace dialog and destroys only the picked item once its effect succeeds (PRTS 卫戍协议/帮助 「达到上限强行佩戴会改为替换装备…并销毁被指定的装备」; GitHub #263, PR #264 by @SpiritedAwayCN, ported); golden as R21D's commit (10 matches: bots using a consumable on a full operator), the merged tree differs from the branch only in R21B's 联防 scenarios
