feat(slice): AP 压速批 8→6——标旗 rush 单轮兑付吞吐主阀门

- action_economy.tres: ap_per_round 8→6；rap_refresh_cost 8→6 随动，保持「满预算停手 = 恰好一刷」耦合不变式（解耦须单独立批）
- smoke_all.gd: 旗回归与轮内刷新两处断言改表驱动（不再写死 AP 值，压速批后自动适配）
- registry: action_economy 条目两值同步并批注（不够再降 4 待观察）
- 根因口径：无伤通关 = 标旗 rush 单轮堆满正向兑付；减伤幅度下调与护甲等级 AC+1 换装未动（见 06 清单）
- 冒烟 211/211 复跑通过（提交前本机验证）
