PatternPropDef gains synonyms? + tier?; the pattern-embeddings bake folds
each prop's @synonyms + declared enumValues (and the description of those
signal-bearing props) into the pattern vector, so an intent word ("bar",
"donut") pulls the pattern whose prop can express it — generalizing the
swap-rank beyond a hand-listed suggestedFor. Chart's chartType annotated as
the first example: synonyms + tier:domain. Registry + embeddings re-baked.
