Adds a 'responses-bg' backend type to the proxy: Anthropic /v1/messages requests are translated to POST /v1/responses with background:true and metadata.completion_window, polled to completion, and synthesized back as Anthropic SSE (with ping keepalive). Tool calls try native OpenAI function format first and fall back to prompt-based emulation on 400. sference.com is registered as a regular backend (-b sf, default model moonshotai/Kimi-K2.6, window via -w/SFERENCE_COMPLETION_WINDOW), plus an env-configurable custom provider (BG_PROVIDER_*). New /_proxy/window control endpoint; /_proxy/status now reports type, window, tool_mode. Also: proxy logs moved to stderr so launchers read a clean port from stdout, origin guard applied to all control POST endpoints, http upstreams supported for self-hosted providers, and macOS-safe ms timing in the benchmark.
