Socket.onAny
Socket.onAnyOutgoing
Socket.volatile
環境: node 22.23.2

assert volatile emit while disconnected discards event immediately without queuing in sendBuffer whereas regular emit is queued
assert onAnyOutgoing and prependAnyOutgoing intercept outgoing event names and payloads when draining buffered events and on live emits
assert prependAny and onAny execute before specific event handlers in deterministic order upon receiving incoming events
assert emitWithAck resolves Promise with server acknowledgement payload and rejects with operation has timed out when timeout occurs
assert callback-based emit with timeout receives Error with operation has timed out and undefined result when unacknowledged
