 * TheSportsDB standings adapter.
 *
 * TODO: Implement when TheSportsDB adds reliable NBA/NHL standings support.
 *
 * Status (as of 2026-03): The free-tier lookuptable.php endpoint is documented
 * as "soccer only" and returns empty results for NBA (4387) and NHL (4380).
 * A premium v2 API key ($9/mo) may unlock broader support — test with:
 *   GET https://www.thesportsdb.com/api/v2/json/lookuptable.php?l={leagueId}
 *   Headers: { "X-API-KEY": process.env.THESPORTSDB_API_KEY }
 *
 * Reference: https://www.thesportsdb.com/forum_topic.php?t=5772
