TestModeTableMatchesFrontendModes 原先写死读 frontend/web/src/lib/types.ts；阶段 0 把该
文件拆成 barrel + lib/types/*.ts 后 MODES 住进了 types/chat.ts ⇒ 测试红。

改为读 barrel + 目录下全部 .ts（新增 frontendTypesDir 常量与 readFrontendTypes 辅助）：
「MODES 住哪个文件」不再是本测试的耦合点，以后再搬也不用改它；barrel 缺失
（backend-only checkout）仍按 fs.ErrNotExist 跳过。

验证：go test ./internal/contract/enums/ 绿；全树 go test ./... = 58 包 ok / 0 FAIL；
gofmt -l 干净。
