Hostname answers in 198.18.0.0/15 are Clash/Surge/Mihomo fake-IP DNS, not LAN destinations. Custom providers that already set allowPrivateNetwork then failed live /models because outbound demanded NO_PROXY and would pin-connect to the fake-IP. Treat hostname-resolved benchmark addresses as non-private and send them through the configured HTTP(S) proxy as a hostname CONNECT. Literal 198.18 addresses and real RFC1918 still require allowPrivateNetwork plus NO_PROXY.

Scope benchmark-address acceptance to proxy-routed provider requests.
resolvePublicAddresses accepts 198.18.0.0/15 for image, video, and lab callers. providerOutboundRequest can also pin that address directly when no proxy is configured. Add an explicit benchmark opt-in and enable it only for configured proxy routing. Keep rejection for direct and generic resolution. Add tests for image/lab rejection and provider no-proxy rejection.

Summary
/modelsdiscovery (and any other provider outbound GET/POST) failed for custom providers such as Packy and Aihubmix on machines that use Clash / Surge / Mihomo fake-IP DNS. Those hostnames resolve to198.18.0.0/15. Write-time validation already treats that as private, so operators setallowPrivateNetwork: trueto save the row. Outbound then refused the request unless the hostname was inNO_PROXY.NO_PROXYrequirement is the wrong control for fake-IP.NO_PROXYpin-connects to198.18.x.x. The working path is a hostnameCONNECTthrough the configuredHTTP(S)_PROXY, the same path a public destination already takes.privateNetwork. If an olderallowPrivateNetworkpath still classifies them as private, outbound still sends them through the proxy instead of throwing.http://198.18.x.xdestinations, real RFC1918 / loopback / metadata, and mixed fake-IP + RFC1918 answers are unchanged. Real LAN providers still needallowPrivateNetworkplusNO_PROXY.allowBenchmarkAddressesstays openai-seed-only. This PR only unblocks outbound after the provider is already saved.Verification
