Events Life Cycle

Handle sport_event broadcast updates when an event is listed, re-listed, or unlisted.

Subscribe to event lifecycle updates

Listen on the tournament_xxx broadcast topic for changes to events in that tournament. The message op value identifies the change:

`op` value	Meaning
`c`	Create an event that is listed immediately.
`u`	Update an existing event, including listing or re-listing it.
`d`	Delete an event by unlisting it.

Event lifecycle behavior

Event state change	WebSocket message
Event created but not listed	No message is sent.
Event created and listed	Send a `sport_event` message with `op: "c"`.
Event listed or re-listed after creation	Send a `sport_event` message with `op: "u"`.
Event unlisted	Send a `sport_event` message with `op: "d"`.
