// Socket.IO emit wrapper.
//
// Replaces the `if(typeof SocketIo != 'undefined')` guards that were scattered
// through the models. Those guards did not just avoid a crash - they silently
// disabled ALL scraping under Jest, which is why none of this code was ever
// testable. Here the no-socket case is a no-op rather than a skipped branch, so
// the surrounding logic runs identically in tests and in production.
