fix(action): enforce truthful quality-gate outcomes

[roli-lpci]

Summary

• add fail-on-error, defaulting to truthful quality-gate failure behavior
• preserve status, failures-json, and repair-status outputs
• distinguish quality-gate/repair outcomes from command or input infrastructure errors
• exercise pass-default, fail-default, and fail-observation behavior in the clean-consumer smoke matrix

Scope

This is PYG-MP-003 only. It does not change repair/comment defaults, changed-file discovery, dependencies, documentation, or the separately queued hidden-artifact uploader defect.

Verification

• actionlint passed
• Ruff and format checks passed
• Python 3.12.13: 158 passed
• deterministic manifest/workflow/output/SHA-pin assertions passed
• final-outcome truth table: 11/11
• gate/repair exit classification: 9/9
• exact two-file diff and diff hygiene passed

The PR's live clean-consumer matrix is the remaining proof for the three public action-step outcomes. Live repair escalation remains unevaluated; its final-step behavior is covered statically without inventing unreliable repair behavior.

Warning

Review limit reached

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

Next review available in: 31 minutes

Limit details: You’ve used all 3 included reviews currently available under your plan.

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.
