fix(web): stale-closure + focus trap + 去边界强转 + a11y/性能打磨 + 类型化客户端

P1-6 useStyleLearn/useKimiOauth 修 stale-closure 依赖。
P1-7 CommandPalette/Drawer 加 focus trap（新 lib/a11y/focusTrap）。
P1-8 SSE 解析与 server.ts 去 as 强转改类型守卫/运行时校验。
P2 删冗余强转、开 noUncheckedIndexedAccess、Toast 清理+稳定 key、列表 key 稳定化、
  rel=noopener、useMemo 大文本、ConflictCard role=group、useInjection 加锁、
  client.test 真断言。
codegen 重生成 schema.d.ts + 消费 DimensionEntry/ReviewConflictView 强类型。
