v0.1.15: 深度审计加固（7 P0 + 20+ P1 歼灭）

【引擎层 P0】
- GameEngine.restore 双重时钟注册（回档后整月双跑）→ restore 重建内核+回置 rng 状态
- engineFromSnapshot 必崩（globalThis.__state 从未设）→ 修正带 seed 重建
- DEV 性能分支二次执行整月管线 → 只读告警（绝不重跑）
- 引擎 advance 遇待决事件死锁 → resolvePending(idx) 通道（自动化/测试推进）

【WorldSim 大修】
- NPC 换代文案垃圾（n-danxin行情降50%）→ 换代快讯专属文案
- secretQi 假闭环（纯写无读）→ 全秘境初始化+missions 统一 consumeSecretQi
- 快讯节流自锁（lastNewsMonth 恒 1 月）→ totalTicks%24
- power 月度收敛坍塌（1400±3）→ 换代/年首化+年度成长
- relation 双重拉零（4 家全 0）→ 交还外交年度漂移
- 市场基准 5 处重复 → POOL_BASE 单一权威；灾年 stale 清理；drift 各池独立噪声
- worldsim 能力卡补全 + normalize 兜底（worldSim/stats 子字段）

【UI/动效/存储】
- ModalShell 三条 CSS 规则真正落地（close 定位/body 滚动/footer 独立底排）——0.1.12 声明未实施项
- fx-canvas：resize 监听移除/mistTimer 清零/reduced 联动/soft 档无雾 + drift 走 gate（过滤器）
- 档位 density 脱钩修复；顶栏“止”钮补 onClick；版本号三处统一 0.1.15
- importAll 清 chronicle 表；自动推进季度落盘（手动逐次）
- 性能：LogFeed memo / Genealogy computeGenealogy memo / Chronicle deps 修正；死码清除（lastPhaseStats/clockFromKernel/哨兵函数等 12 处）
- 删除误入库的“p”游离文件

【测试】979 全绿（36 套件）；金钟罩三档 0.1.15 基线固化；
