"""Provider detection tests — _detect_provider real hosts and false-positive rejection (re: #768).
These import the *real* helpers from ``src.llm_core`` (not local copies) so a
regression in hostname matching is actually caught. The point of the change
under test is that provider detection keys off the URL's *hostname*, not a
substring of the whole URL — so a domain appearing in a path/query, or a
look-alike host, must not be misclassified.
