Completion items dressed in colors fair! ✨

The title accurately identifies the component (nvim-cmp) and the aspect being modified (icons/icon highlights). While the title is somewhat brief and general rather than providing granular details about the specific nature of the changes (adding icon-variant highlight links), it is sufficiently clear and meaningful to convey the primary purpose of the PR to someone reviewing commit history.
