What

Follow-up to #288 (merged). Moves the deploy.yml concurrency from the workflow level to the deploy job, and flips cancel-in-progress to false.

Why

The merged version used workflow-level cancel-in-progress: true. That can cancel an in-flight production deploy when a newer push to master arrives — and if that newer push then fails a check, neither commit deploys, leaving production un-updated even though the earlier commit was good.

This is the same P1 Greptile flagged on the sibling Dropbox integration PR. #288's only Greptile review predated the switch to true, so it was never surfaced here.

Fix

  deploy:
    ...
    concurrency:
      group: deploy-production
      cancel-in-progress: false

Deploys now serialize (a newer push waits) and a running publish is never interrupted. No check-cancellation is lost that matters — merges to master are infrequent, and every one gets checked and deployed in order.

OUT-4184

[greptile-apps]

Confidence Score: 5/5

This PR appears safe to merge.

What we checked:

• Active deploy cancellation: No. The deploy jobs share one queue, and cancel-in-progress is false.

Summary

Production deploys now wait for one another instead of canceling an active publish. Older queued runs check whether a newer commit is already on master and skip publishing when they are stale.

• Moves production concurrency from the workflow to the deploy job.
• Keeps active publishes running while newer deploys wait.
• Skips stale queued runs before they publish older code.
