Registry: when several model detectors match a path, the first registered match still wins (main's pinned precedence, e.g. test_local_manifest_detectors_keep_first_match). Path specificity against each entry's registered HF paths now only decides whether to warn: the resolution is silent when the first match is strictly more specific than every other match (e.g. LTX-2.3 distilled directories that the LTX-2 base detector also claims through the shared pipeline class name), and warns otherwise, including when a later match is more specific than the one chosen. The PR originally re-ranked matches by specificity; that changed main's tested first-match resolution for local manifest directories, so it was narrowed during maintainer review (Swarm order #720).
Also fixes the QAD weights file path.
