TypeScript crosstest runner child process cleanup hardening, loop 0, final verdict PASS.

## 루프 이력

| Plan | Review | Verdict | 메모 |
|------|--------|---------|------|
| `plan_cloud_G07_0.log` | `code_review_cloud_G07_0.log` | PASS | 네 TypeScript crosstest runner에 process group-aware kill과 bounded stream join이 적용됐고 검증을 통과했다. |

## 구현/정리 내용

- `typescript/crosstest/typescript_dart.ts`, `typescript_go.ts`, `typescript_python.ts`, `typescript_kotlin.ts`의 client subprocess timeout cleanup을 POSIX process group kill 우선, direct kill fallback 구조로 정리했다.
- stdout/stderr stream completion 대기에 5초 timeout을 적용해 subprocess 종료 후 stream join이 무한 대기하지 않도록 했다.

## 최종 검증

- `npm run check` - PASS; `tsc --noEmit` exit code 0.
- `npm test` - PASS; Vitest 5 files, 34 tests passed.
- `./node_modules/.bin/tsx crosstest/typescript_dart.ts` - PASS; all typescript-server/dart-client crosstests passed.
