`intent_search`Search the Canadian catalogue by a natural-language description of a NEED rather than keywords. Give it what the shopper actually wants (e.g. 'a quiet gaming laptop under $1500', 'a reliable stroller for travel') and it returns the best-matching products with their current price (CAD), Lowvyn Score, and Deal Verdict, plus what it understood (category, budget, must-haves). A relevance model does the matching; the deterministic deal gate decides the verdict — it never inflates a deal. Use this when the user describes a use case, budget, or constraints instead of naming a product; use search_products for a plain category/price filter. Each result carries an id + canonicalUrl you can pass to get_product, verify_deal, or find_cheaper.	Search the Canadian catalogue by a natural-language description of a NEED rather than keywords.
