Split the proxy into two long-lived httpx clients: an RPC client for short JSON control calls and a proxy client for streaming/large bodies, both closed once via aclose() on shutdown (wired from the admin lifespan). host_proxy and http_proxy now reuse the shared proxy client instead of opening and closing a client per request, reusing pooled connections. Tag metrics with worker_pid so per-worker series stay distinct. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
