`time.After(ProbeTimeout)` returned a single channel shared by every probe goroutine in the cycle. Only the first goroutine to receive the deadline tick drains the channel; any other goroutine still waiting on its `responseCh` is then stuck forever, `wg.Wait()` never returns, and the scheduler loop in `app.go` stalls on the next tick. The condition fires whenever two or more nodes time out in the same cycle — common under cable-pull where IsOnline lags reality and both routers stay in the candidate set as half-open TCP. Move the timer inside each goroutine so every probe has its own deadline. Updates #3234
