ToClientTag

All WebSocket messages sent by the server to the client begin with a ToClientTag byte. This enum is non-exhaustive only to avoid Illegal Behavior when malformed messages are sent over the socket; unnamed tags are an error condition and should terminate the connection.

Every tag has a curresponding extern struct representing the full message (or a header of the message if it is variable-length). For instance, .hello corresponds to Hello.

When introducing a tag, make sure to add a corresponding extern struct whose first field is this enum, and check its layout in the comptime block above.
