Greptile Summary

This PR is an automated Mergify migration that upgrades .mergify.yml from the deprecated pull_request_rules + post_check action pattern to the newer merge_protections top-level key. The two existing approval rules (one for Lookout UI changes, one for general Armada maintainer approval) are preserved with identical success_conditions logic; only the structural wrapping and the title display field (which has no equivalent in the new format) are changed.

Key points:

• Prerequisite before merging: The merge_protections Mergify product must be explicitly enabled in the repository's Mergify dashboard. The PR description itself warns that merging without enabling it will cause both protection rules to stop working, leaving the repository with no approval enforcement.
• Logic is faithfully preserved: The success_conditions blocks are identical to the old post_check success conditions — the conditions key is renamed to if, and the action wrapper is removed.
• if gate behaviour: Both rules retain if: "#approved-reviews-by>=1", meaning they are only evaluated once at least one approval exists. This is the same behaviour as before but worth noting — PRs with zero approvals will not have either protection triggered.

Confidence Score: 3/5

• Safe to merge only after enabling the merge_protections product in the Mergify dashboard; merging first would leave the repository without any active approval enforcement.
• The migration logic itself is correct and faithfully reproduces the old rules in the new format. The score is reduced because there is a hard external prerequisite (enabling merge_protections in the Mergify dashboard) that must be completed before this PR is merged, otherwise both protection rules will silently stop working. This is explicitly called out in the auto-generated PR description but is easy to overlook.
• .mergify.yml — the only changed file; verify the merge_protections dashboard feature is enabled before merging.
