NPCLocal now maps the words people actually type to the right trade category

We pulled hundreds of real search terms from NPCLocal and found where they dead-ended. Type 'drain cleaning' and the old system gave nothing useful because the category is labeled plumbing. Type 'clear aligners' and you missed orthodontists entirely. We connected those plain-language terms to the right categories, so carports finds carport builders, hearing tests finds hearing aid shops, and drain jetting finds plumbers. The fix matters most in smaller towns where a search that goes nowhere is worse than no directory at all.
