Llama.cpp server now routes all model loads through a queue

The official source reports this update: b11114: server: fix router eviction races with the existing queue. server: fix router eviction races with the existing queue ( #29217 ) server: route every model load through the queue A model loaded by the fast path has no queue entry, so tick() evicts it at its LOADED transition before its own request is proxied. Every load now joins the queue, whose entry protects the model until its waiters leave. server: do not admit requests into a stopping model A request for a model that is being stopped still sees it LOADED and is proxied into the dying child. Such a request now joins the queue and is served by the next instance.
