Adding labels to PR based on their title

Editor assessment

The subject states the automation plainly: PRs are labeled based on their titles, with the issue reference conventionally attached. The mechanism and its input are both identified without the diff. The feat type is defensible for a new automation even though ci would fit; the rubric tolerates straddling choices. No scope or body is present, and neither is demanded for a labeling-rule addition; the title-based trigger carries the design. Style is clean apart from the gerund phrasing. Good and publishable.
