DataChannelOpenEvent
Fired by Dart when it opens a DataChannel for a control. Carry the
channel id (Dart native port in embedded mode, monotonic u32 in muxed
fallback) plus a user-defined channel_name so widgets that open
several channels can dispatch.
Note: the field is channel_name, not name, because Event.name
already carries the event's own name ("data_channel_open").
