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。
