* [client] Coalesce peer list change notifications to the mobile listener Every peer state change spawned a goroutine to call the platform listener. During a reconnect storm this pinned hundreds of OS threads in JNI and let the UI call back into the engine from each of them. Deliver peer list changes from a single goroutine per listener and collapse pending changes into the latest count. * [client] Cover a pending wake-up when the peer list deliverer is replaced The replacement test waited for the old callback to finish before swapping listeners, so it never exercised the stop check that runs after a wake-up. Block the old callback, queue a peer list change and swap while it is blocked, then assert the old listener never sees the new count. * [client] Signal peer list deliverer exit and wait for it in the test The replacement test sampled the old listener after a fixed sleep, so a late stale delivery could slip past it. Close a done channel when the deliverer goroutine returns and let the test wait on it instead. * [client] Drop the test-only peer list deliverer exit channel The done channel was only read by the replacement test. Production code cannot wait on it, since joining the deliverer would block on a mobile callback. The tests now drive the deliverer loop directly and check that setListener and removeListener close its stop channel.
