fix(release): authenticate iii installer

[ytallo]

Summary

• pass the workflow token to the iii installer during Registry publication
• add a release workflow contract test for the authenticated installer configuration

Why

Release publication could fail before starting the iii engine when the installer exhausted GitHub's unauthenticated API limit. The workflow already has read access to repository contents, so using the ephemeral workflow token raises the API limit without adding a new secret.

This unblocks exact Registry publication and keeps failed mutating releases recoverable through Release Control.

Validation

• release workflow contract tests
• YAML parse and token wiring assertion
• authenticated iii 0.17.0 installer run

Warning

Review limit reached

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

Next review available in: 28 minutes

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

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.
