This change addresses breakage in radio search and playlist retrieval by switching requests back from the newer api.radio-browser host to the older www.radio-browser endpoints for now. It also fixes resume-search behavior by saving the active search URL at the point where a valid JSON result set is returned, and updates curl requests to identify the client as ziptuner/0.2 instead of the default sample agent. The net effect is a more reliable search flow while the newer Radio Browser API migration is still being worked out.
