v0.1.8: 万物皆是插件 + 全应用审计修复（60+ 缺陷歼灭）

插件协议：
- CotycPlugin Manifest（dependencies/conflicts/protected/install/uninstall）
- PluginManager：安装序确定性/依赖拒绝/异常回滚/追踪型上下文（卸载全摘钩子）
- 三核心插件常驻（Systems/Data/Events）；插件清单/安装移除/启停广播
- EventPoolRegistry 多池合并；facade about/query('plugins')/plugin 订阅
- 设置页插件清单（含卸载按钮、核心保护）；examplePlugin 开发范本入仓

全应用审计修复（引擎 39 + UI/主进程 40 双路清单，P0→P2 歼灭）：
- P0：单亲 rollRoots 崩/插件事件软锁（findEvent 查池）/fire 覆盖幸存事件/
  facade 未赋值（act 目录 6/24 生效→全量接通）/packOverride 死实现真接管/
  4 能力卡无接线（trib/apprentice/tournament/season）/读档 rowid 方言崩溃/
  buildApprentice 空候选崩/插件安装无回滚/trait 加成从未消费/DEV 双跑破坏时序
- P1：定时器幸存/advance in-flight 闸/battle 暂停/tournament 点将真传/
  史书 memo 依赖/面板 hooks 顺序违规/远征 squad 残留 id/跨档状态残留/
  toast 自清除/读档错误提示/导入后重载世界/pendingEvent 读档回填
- P2：版本三处统一/NewGame 随机收编/学费错误文案/姓氏池去重/
  功法品阶错位（凡阶哨兵）/功法定价对齐/market 白名单校验/
  战利功法去重/回声漏封缄/clock 迭代快照/core 事件池保护/
  渡劫陨落走真突破/寄读 desc 诚实化/doas 死代码清理等 30 项

测试 239→256；金钟罩复验（防御批零漂移）
