v0.1.9: 百年报告 & 发布之窗（报告/迁移/阵型/冬祷/哨兵）

- 百年族史报告：buildReport 纯函数（人口/声望/战力三线、死因榜、突破密度、
  大比战绩、代际长度带）+ 春秋原 SVG 折线视图 + 自动措辞结语
- 存档迁移管线 v2：migrate 链（v1→v2）+ 未来版本拒载（TOO_NEW）+ 导出信封
  带 appId/schemaVersion + 导入全链路迁移校验；saveState 自动写 CURRENT_SCHEMA
- 战斗阵型：锋阵(+10%攻)/雁阵(御5%+溃伤-15%)/蛇阵(溃伤-30%)，三处出战接入
  （遣队/大比/劫掠）点将面板下拉 + 战报首行标阵
- 冬至岁祷：每年十一月三选（观星+3声望/祈福全族修为/问卜吉凶）
- 发布准备：scripts/verify-release.mjs 验收哨兵（npm run verify/verify:package）
  + README 全面重写（架构/守护/版本沿革）；版本号三处归一
- 测试 861→881（报告四例/迁移五链/阵型六则含胜率统计/冬祷四则）；
  金钟罩三指纹零漂移；typecheck/build 通过
