ci(deploy): CloudFront 라우팅 함수 코드 자동 동기화

[yuchem2]

요약

정적 export 라우팅용 CloudFront Function(convene-rewrite) 코드를 배포 파이프라인에서 자동 동기화한다. 지금까진 콘솔에 수동으로 붙여넣어 publish 해야 했다.

설계 노트

• 런타임(cloudfront-js-1.0/2.0)을 하드코딩하면 LIVE 함수를 깰 위험이 있어, describe 로 가져온 기존 FunctionConfig 를 그대로 되돌려 코드만 교체한다.
• behavior Associate(Viewer request 연결)는 1회성 콘솔 작업이라 자동화에서 제외.

Code Review

This pull request introduces a CloudFront Function (infra/cloudfront-rewrite.js) to handle static export routing corrections, rewriting dynamic routes to placeholder HTML files and appending index.html to directory paths. The review feedback correctly identifies compatibility issues with the cloudfront-js-1.0 runtime (ES5.1), pointing out that ES6 methods String.prototype.includes and String.prototype.endsWith are unsupported and will cause runtime errors. The reviewer provided actionable suggestions to replace these with ES5-compatible alternatives like indexOf and slice.
