Fixed SSE and chunked streaming stutter caused by buffering under 1 MiB in mitmproxy.

Full changelog

Unblock SSE / chunked streaming through mitmproxy. The --set stream_large_bodies=1m flag (added to prevent OOM on large downloads) buffered any response under 1 MiB before forwarding, stalling LLM SSE and chunked streams of small chunks until the stream ended or the threshold was hit — producing perceptible stutter downstream. Introduces a bundled system addon, always loaded by the egress launcher, that forces flow.response.stream = True for responses with content-type: text/event-stream or transfer-encoding: chunked. Large-body OOM protection from stream_large_bodies stays intact for everything else. The previous example script add_header.py is renamed to system.py and repurposed as the always-on system addon (wire-transparent: no headers added or altered). User-supplied addons via OPENSANDBOX_EGRESS_MITMPROXY_SCRIPT are still loaded after the system addon and may observe or override its hooks. (#898)
