test(presenter)+fix(i18n): 淘汰策略与共享缓存解耦；注释里的 ASCII 引号
- prune() 抽成独立函数：全局缓存被所有用例共享，谁往里面灌 240+ 条都会顺手清掉 别的用例刚缓存的键（实测：并行跑时 the_second_identical_refresh_... 假红）。淘汰 策略改在本地 Cache 上测，两条判据各自确定； - clippy -D warnings：from_ref 代替 &[x.clone()]； - model.rs 注释里的 "原因 + OS 原文" 用 ASCII 引号 → 页面字面量白名单守门报红，改 中文引号；core/events 的三处文档失真登记为 TowerFinding（scope 外）； - 出处文案口径：TooLarge 的 detail 只留数字（presenter 不产人读文案）。
