Phrases don't dangle on an open-vowel stopword tail

"smell like a" was matching "myself why" (EH-AY) because mosaic triples
were never weak-flagged — a trailing article "a" (bare open vowel)
dangles and isn't part of the rhyme. Triples now skip an open-syllable
stopword tail, while closed ones ("mean to it" -> theme music) stay.
