This updates XMonad.Prompt.Unicode to actually use the caller’s XPConfig matching and sorting behavior instead of hardcoding its own search logic. The prompt now threads searchPredicate into Unicode name matching and adapts the configured sorter to work case-insensitively with the uppercase Unicode data it searches against. In practice, custom completion behavior like fuzzy matching or alternate ranking now works for Unicode prompts too, making them consistent with the rest of the prompt ecosystem.
