Introducing the Merge Queue - Shopify

Introduced Shipit's merge queue to automate the process of merging pull requests into the main branch, reducing manual intervention and improving developer workflow. Implemented a browser extension to integrate the merge queue into the GitHub pull request interface, making it the default merging mechanism. Added configurable thresholds for branch divergence to discourage long-lived branches. Enhanced the merge queue to automatically handle pending CI statuses, merging or rejecting pull requests based on results. Developed features for marking commits as unsafe for deploy and automatic revert detection to improve the safety and automation of the deployment pipeline, especially in the presence of bad commits or reverts.
