Move delay before broadcasting to clients
Replace per-socket 5s wait with a single 4s pause before iterating
clients to avoid per-client staggering and reduce total delay Move delay
before broadcasting to clients
Wait 4s before fetching broadcast payload and reuse the results for all
matching clients instead of delaying per-socket. This avoids redundant
data retrieval and reduces overall broadcast latency.
Wrap Effect pipelines in getScrobbles, getScrobblesChart and
getActorScrobbles with Effect.runPromise so they execute and return
promises.
