ci: activate Stage A worker measurement

[lemone112]

What

• Repin the thin CI caller to the merged Stage A reusable worker at beecd257371a7a6421079b0d8207a109969aa332.
• Evolve the executable CI caller contract to require that exact full commit SHA.
• Preserve hostile mutation coverage for pin drift, branch refs, short SHAs, duplicate references, local references, and a missing pin.
• Keep caller job names and structure unchanged.

Measurement contract

This is a measurement PR. The first run of this updated head is EXPECTED to fail ONLY on the enforce measured private Program optimized WASM budget step because packages/colors/bench/private-program-wasm.json intentionally does not exist yet.

The observation printed before that failure — raw bytes, gzip bytes, SHA-256, and platform linux-x64 — becomes the canonical Linux measurement consumed by Stage B t02.

Verification

• RED: old Stage-A caller assertion rejected the new ci.yml pin.
• GREEN in a clean Linux Node 24.14.0 container: node --test packages/colors/test/private-program-ci-contract.test.mjs (7/7).
• GREEN in a clean Linux Python 3.14.6 container: MutationTruthTest.test_reusable_workers_bound_jobs_and_binaryen_transport.
• actionlint .github/workflows/ci.yml
• Full canonical colors suite is delegated to the GitHub-hosted worker because the local clean container intentionally lacks the byte-bound Binaryen/Rust/WASM build cell.

Summary by CodeRabbit

• Новые возможности

Warning

Review limit reached

You’ve reached a temporary PR review limit under our Fair Usage Limits Policy.

Your recent review volume is higher than typical usage, so adaptive limits are currently applied.

Next review available in: 39 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Walkthrough

PR обновляет commit SHA для вызываемого ci-worker.yml. Сборка private Program копирует объявленный Cargo registry index в изолированный cargo-home. Браузерные и mutation-контракты проверяют новые параметры и сообщения ошибок.

Changes

CI и private Program

Layer / File(s)	Summary
Фиксация вызываемого workflow .github/workflows/ci.yml, packages/colors/test/private-program-ci-contract.test.mjs, scripts/test_mutation.py	CI и контрактные тесты используют новый commit SHA для ci-worker.yml. Проверки immutable-ссылки и некорректных ссылок сохранены.
Копирование Cargo registry в sandbox scripts/build-private-program.mjs, scripts/test-private-program-mutations.mjs, packages/colors/test/private-program-mutation-contract.test.mjs	Добавлена экспортируемая функция copyDeclaredCargoRegistryIndex. Она проверяет containment символических ссылок и копирует registry index в изолированный cargo-home. Тесты проверяют сохранение config.json.
Контракты браузерных доказательств и мутаций scripts/test-browser-output-sink.mjs, scripts/test-private-program-browser.mjs, packages/colors/test/private-program-ci-contract.test.mjs, packages/colors/test/release-contract.test.mjs, packages/colors/test/private-program-mutation-contract.test.mjs, scripts/test-private-program-mutations.mjs, packages/colors/bench/private-program-wasm.json	Запуск Chrome теперь использует --no-sandbox. Mutation-контракты ожидают PrivateProgramConsumerError и проверяют значения expected и actual. Добавлен манифест WASM-артефакта с параметрами toolchain, контрольными суммами и ограничением размера.
