Class Method Summary

• .find_closest_match(target : String, candidates : Enumerable(String), max_distance : Int32 = 3) : String | Nil

  Finds the closest matching string from candidates, or nil if distance > max_distance

• .levenshtein_distance(s1 : String, s2 : String) : Int32

  Levenshtein distance calculation for fuzzy suggestions
