Build a CompleteResult by case-insensitively prefix-matching prefix
against candidates. The matches populate values, total is set to the
match count, and hasMore reflects whether the spec's 100-item cap
truncated the set. This is the built-in helper for the common
autocompletion pattern, so consumers do not hand-roll startsWith.
