chore: upgrade Node to 24 LTS

[Yeom-JinHo]

Changes

Vercel의 Storybook 배포 실패를 해소하고, 개발/CI 툴체인을 Node 24 LTS로 올립니다.

변경 내용

파일	변경
package.json	engines.node ">=22.22.2 <23" → "24.x"
.mise.toml	node 22.22.2 → 24.19.0
package.json / packages/tokens/package.json	@types/node → ^24
pnpm-lock.yaml	@types/node 22.10.1→24.13.3, undici-types 6.20.0→7.18.2
AGENTS.md	개발 명령어 주석의 Node 버전 안내 갱신

"24.x" 표기를 선택한 이유

Vercel 문서상 >=24 같은 열린 범위는 "사용 가능한 최신 메이저"로 매핑됩니다(>=20.0.0 → 최신 24.x). 즉 >=24로 두면 Vercel이 26.x를 builds에 추가하는 순간 예고 없이 26으로 점프합니다. 24.x는 결정적이고, 26으로 갈 때 의도적으로 한 줄만 바꾸면 됩니다.

Visuals

해당 없음 — UI 변경 없습니다. 컴포넌트 코드, 디자인 토큰, 스타일 모두 미변경입니다.
