fix(release): bind artifact build to exact tag checkout

[seonghobae]

Closes #325.

Boundary

This Draft starts from protected main@e8109ec2a17de8bd6594487aa12c8c8a93cb2c03. It is a release/supply-chain evidence repair only. Owned paths are exactly .github/workflows/release.yml and src/releaseExactCheckout.test.ts. Keep it Draft/unmerged while #118 owns exact v0.6.0 source identity unless that release boundary independently accepts this repair before tagging.

RED → GREEN

RED: test-only cf64209e5dcd826f0baf2bc52aa9aad65d7a8f1f. Hosted CI run 31819437652 reached frozen install and typecheck successfully, then failed the intended releaseExactCheckout.test.ts assertion because build-release-artifacts did not explicitly check out ${{ github.sha }}. No source workflow repair was present on that head.

GREEN: exact head cbab679fcd8d713ec053c1c3d80e5ec4c7b5004a. The workflow repair is deliberately narrow:

• artifact build checkout pins ref: ${{ github.sha }};
• checkout credentials are not persisted;
• an immediate git rev-parse HEAD equality assertion binds the working tree to the event SHA before pnpm/Node/Python setup or repository-code execution.

The PR diff contains no other release.yml change.

Hosted CI run 31819848324 completed successfully on exact GREEN head cbab679.... Its build/test job passed frozen install, typecheck, 100% coverage, library build, packed-package consumer verification, and demo build; Office and cross-engine browser jobs also succeeded on that exact SHA.

Preserved release authority

The existing tag-only trigger, current-main-tip equality gate, pinned actions, immutable lock installs, package/demo/Office/browser checks, SBOM/checksum/provenance attestations, GitHub release immutability verification, npm/PyPI OIDC Trusted Publishing, public registry digest verification, and exact four-asset inventory remain unchanged. No permission, credential, release-identity, model/provider, persistence, network-service, deployment, or host-authority expansion is introduced.

Merge boundary

Do not count queued/pending/absent central evidence as passing. Current live rules still require qualifying independent approval, last-push approval, review-thread resolution, and all required central workflows. This PR remains Draft and must not publish, tag, or create release identity.

📝 Walkthrough

Walkthrough

릴리스 워크플로가 github.sha를 기준으로 소스를 체크아웃하고 자격 증명을 보존하지 않습니다. 의존성 설정 전에 실제 HEAD를 검증합니다. 전용 Vitest 테스트가 체크아웃, 검증 순서, prerelease 태그와 npm 게시 조건을 확인합니다.

Changes

릴리스 체크아웃 및 태그 검증

Layer / File(s)	Summary
릴리스 워크플로 검증 강화 .github/workflows/release.yml	build-release-artifacts가 github.sha와 전체 이력을 사용해 체크아웃합니다. 자격 증명 저장을 비활성화합니다. 의존성 및 런타임 설정 전에 실제 HEAD가 기대한 SHA와 일치하는지 검증합니다. 기존 immutable release 검증 흐름은 유지됩니다.
워크플로 회귀 테스트 추가 src/releaseExactCheckout.test.ts	테스트 보조 함수가 워크플로 작업과 단계를 추출합니다. 테스트가 체크아웃 설정, 검증 순서, 자격 증명 비보존, prerelease semantic version 태그 허용 및 하이픈 없는 ref에서의 npm 게시 조건을 확인합니다.

Merge Risk: 🔵 Low · up to 0623c

This PR makes release artifact builds check out and verify the exact event commit before execution, reducing the chance of publishing artifacts from the wrong source. A bounded risk remains because the regression test may not detect if those controls are moved to the wrong workflow step, so the change is mergeable with explicit owner follow-up.
