This commit introduces Mergify, a powerful bot designed to assist with
automated merging and other CI-related tasks. As an initial step, we
enable a basic feature: automatically notifying users when a pull
request has merge conflicts.
When a conflict is detected, Mergify will add a label to the PR. This
label will be removed once the conflict is resolved.
In the future, we plan to expand Mergify’s role to include auto-merging,
as discussed in #1667, once the project is ready.
