inferParamBFromIdOrName used a consuming trailing boundary `b(?:[^a-z0-9]|$)`,
so when two `<num>b` parameter tokens are separated by a single delimiter
("8b 70b", "8b-70b"), the first match ate the shared delimiter and the second
token's required leading boundary had nothing to match, silently skipping it —
returning the first (often smaller) size instead of the largest. Make the
trailing boundary a non-consuming lookahead.
