feedback1 WA: Lappland counts her own first refresh; Mutation Cell is not consumed

Player reports after 0.1.0, #1 and #4.

#1 拉普兰德 (garrison_123, SERVER_GAIN_BOND_LAYER_BY_REFRESH_CNT) checked the
player's refresh count of the round, so a copy bought after the round's first
manual refresh never stacked that round. Players report the official
behaviour: the first refresh after acquiring her also stacks. Each copy now
counts the manual refreshes it witnessed this round (board or hand) through a
per-piece round counter (PlayerState.pieceRoundCount, ctx.incPieceCounter); an
elite merged this round keeps the highest count of its copies [ASSUMED]. The
"本回合每刷新过1次" multiplier traits keep the player's count.

#4 突变细胞 destroyed itself after one transformation. Official text never
says 销毁 (every consumable's does), PRTS notes "原干员销毁，获得一名高一阶的随机
初始干员", and players re-inject the cell every round. The built-in now replaces
the carrier with a random normal operator one tier higher (max 6) and returns
the carrier's equipment, the cell included, to the hand
(transformChess returnItems); the content override is gone. The item card
shows the rule (items.json note, build-data ITEM_RULES); bots inject their
least valuable single normal operator below tier 6 (bot.js cellTarget).
