// registerYourID sends two signals on every new connection:
//
//  1. wsts/hello — version handshake. The SDK checks this version against its own
//     constant (sdk/version.js) and refuses to proceed if they differ. The codecs
//     list advertises which frame encodings the server supports (0 = JSON, 1 =
//     binary once #42 is ready). This signal is sent first so the SDK can gate
//     all subsequent processing on a successful version check.
//
//  2. id — the client's own socket id, exactly as the original Node YourID did.
