fix(topic-hubs): word-boundary hub-keyword matching so a mid-word substring can't mis-file an article — 'bank' no longer tags Burbank as lenders-banks, 'mall'∉small, 'sale'∉wholesale, 'loan'∉Sloan. Leading-\b keeps intentional prefixes (refinanc→refinancing, bank→bankruptcy); space-padded ' ai ' stays a whole word
