Exposes the number of connections currently waiting in the kernel's accept queue for the server's listening sockets how many clients have connected but haven't been picked up by the app yet. Backed by Iodine.queued_connections, which walks Iodine's own listeners and reads each one's queue depth from the kernel. Meant to be sampled on a timer via Rage::Telemetry.every, the same way GC stats are, so it can be reported alongside other reactor health metrics. Adds two specs: one confirms the reported count matches the number of connections actually parked in the queue, the other confirms the method works correctly when called from inside a .every block.
