Adds three pieces needed to build one KPN network and reuse it across many replays/configs instead of tearing down and rebuilding per run: - Channel<T>::push_blocking (+ IVariantChannel/VariantChannel forwarding): lossless backpressure push that waits for space instead of dropping when the ring is full. PyNode's run_loop now uses it so a downstream consumer lagging behind never silently drops a frame. - PyNetwork::node_ptr / node_stats: raw node handle by name (for a binding to dynamic_cast to a concrete wrapper and call functor-specific runtime setters) and a per-node timing snapshot for profiling. - ObjectVariantNodeWrapper: variant-node adapter for functors that need runtime-constructed state (a Config, a loaded gallery), mirroring VariantNodeWrapper's channel plumbing but backed by ObjectNode<Obj>. Built and used downstream in scene-actor-extraction's sae_kpn Python replay bindings for repeated threshold-sweep evaluation of the same pipeline.
