ci: require stable PR gate checks

[proerror77]

Closes #344

Change contract

Main PRs always publish stable Monorepo and Prediction Markets gate checks; each gate fails whenever a selected dependency does not succeed, while selector-skipped jobs remain non-blocking.

Acceptance evidence

The new gate jobs run on every pull request, aggregate all conditional jobs, and reject failed or cancelled selected jobs. Main branch protection requires these gates plus the existing Security Summary Report and one fresh approval.

Out of scope

Research snapshot construction, evaluator/MCTS execution, collector deployment, catalog changes, and live execution policy.

Dependency / merge order

None. This is the prerequisite gate before #319.

Focused validation

• shellcheck .github/scripts/verify-ci-gate.sh .github/scripts/test-select-rust-ci-scope.sh
• bash .github/scripts/test-select-rust-ci-scope.sh
• go run github.com/rhysd/actionlint/cmd/actionlint@v1.7.7 .github/workflows/ci.yml .github/workflows/ploy-ci.yml
• git diff --check

Rollout / rollback impact

Rollout: main protection is enabled with the three required GitHub Actions checks and fresh approval. Rollback: revert this PR and remove the two required gate contexts before merging the revert.

Warning

Review limit reached

@proerror77, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 33 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

Walkthrough

Adds a shared CI gate verifier, integrates it into the main and prediction-markets workflows, broadens workflow triggering, and tests successful, skipped, failed, and cancelled job-result handling.

Changes

CI gating

Layer / File(s)	Summary
Gate verifier and test coverage .github/scripts/verify-ci-gate.sh, .github/scripts/test-select-rust-ci-scope.sh	Adds JSON-based result validation and tests acceptance of successful or skipped jobs plus rejection of failed or cancelled jobs and required workflow wiring.
Main CI workflow gate .github/workflows/ci.yml	Adds the always-running ci-gate job and removes the prediction-markets push path exclusion.
Prediction markets workflow gate .github/workflows/ploy-ci.yml	Removes the pull-request path filter and adds prediction-markets-gate over the workflow’s CI jobs.

Estimated code review effort: 3 (Moderate) | ~20 minutes
