engine: a Hanja reading answers with the words it begins

hanjaquery matched the reading exactly, so a word was reachable only
once every syllable of it had been typed, and the popup went blank on
the way there.  Measured over map/hanja.dict's 187,304 readings:
95,024 proper prefixes of a word answer with nothing today, and 66,731
of those are the keystroke just before the word completes -- 대한민 is
one, so 대한민국 looks absent until the last key lands.

dictprefix walks the entry at a node before its children, so the
reading's own conversions keep their place and the words follow: 34,441
readings gain candidates and none of the 187,304 has its existing order
changed.  A jamo reading is untouched, since the two keyspaces do not
meet and ㅁ has no children.
