[AminChirazi]

Demo

Feature name: Engineering workflows review packages
This pull request connects engineering-workflows to the complete advisory Operator PR-package lifecycle. The review package produced by this pull request is the smoke test; there is no application UI change or recorded media.

Non-developer review: https://operator.automators.com/engineering/review-packages/f41b6d44-f885-43a6-a9e5-b8d1b4109383/revisions/1 — same demo and description on Operator, comment there if you don't use GitHub.

Why

Feature work in engineering-workflows should be reviewable from Operator, with requested reviewers and final shipped or cancelled state synchronized automatically.

What you get

• All six required pull-request events and both pull-request-review events.
• Explicit contents-read and pull-request-write permissions.
• Reviewer synchronization and automatic ship/cancel lifecycle reporting.
• An advisory workflow that does not gate merges.

Verification

The pass signal is a Review: https://operator.automators.com/engineering/review-packages/... line in the job log and a **Non-developer review:** line added to this body.
